Another question is that is httpd uses threads (as provided by FreeBSD) starting a new thread will or will not copy executable copy and data? Basically, will a new thread eat another 4300K or just a little bit for its data? SIZE is the total amount of virtual memory that a process has allocated. This includes text, data, and stack. It also includes all the stuff that's shared with other processes (mostly through the use of shared libraries). RES is the amount of physical memory in use by the process and will only include that part of a process's virtual memory space which is currently allocated in physical memory. Unfortunately, freebsd does not appear to track the amount of shared virtual memory for each process. It could be obtained by walking through all the pages in a process's vm map, but that would really slow top down. I don't know of any freebsd utility that would give that information for an individual process. But hey, if it's out there somewhere where it is easy to grab, I would be very happy to add it to top. My knowledge of VM system of FReebSD is so low, that even though i can write in C i don't know where to start here. I haven't found anything ready for this. make search in port on 'memory' and 'ram' does not return much. All this i need to calculate maximum possible number of https i can run on a box with certain amount of memory and select proper MPM for Apache.

You're not just going to be able to sit down and plug numbers in to a formula and say voila!. You will have to observe how httpd performs in your particular environment to see how many page faults per second it generates and decide for yourself the point at which X pf/s is too much. Of course, but i need to start with something instead of just pure guess out of the blue. Personally, based on my experience, I would be more concerned with the amount of available cpu cycles than memory. CPU is more than just enough in my case. There will a a lot https sitting there but load, i am sure, will be low. Swapping is simply unacceptable, so i am counting only real physical ram. However, noone mentioned anything about threads.

ISTM that it would be better to use kern.hz=100 in this case. My reasoning is that a web server shouldn't be terribly sensitive to latency, so it's better to have longer quantums to get more work done without context switching overhead. If you're not using polling, you'll be getting interrupts for network traffic anyway. That what i personally thought. However 100 seems to be too rough. I just feel so, no reasoning behind this ;) Maybe 200-300 is better than 100 and better than 1000? I wonder how to build a test case for this to find best settings for web server, so others will not stuggle with this on the future.

Re: Quation about HZ kernel option
effect. I would not go under 100, though. I personally believe that a default of 1000 is ridiculously high, especially on a SMP system. Nuts! Everybody has his own opinion on this matter. Any idea how to actually build syntetic but close to real benchmark for this? For example: Usual web server does: 1) forks 2) reads a bunch of small files from disk for some time 3) forks some cgi scripts 4) dies If i write a test in C doing somthing like this and run very many of then is parallel for, say, 1 hour and then count how many interation have been done with HZ=100 and with HZ=1000 will it be a good test for this? -- Regards Artem ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Ofcourse you'll break your traffic flow that way, since latency will increase. You seem very upset about it, are you sure you want to use polling(4)? it uses much more resources than interrupts. I am not upset about all this. But i want to understand why is it doubled. Because when i turn on polling i think that timer freq supposed to be just like i set HZ. However, actually, i am now thinking about another issue. I have dual CPU with HT. If i turn on HT (and it does help in my case) it shoud 2000 int x4 = 8000 ints per second.

It explains a lot:) Yes, i have read the man for polling. However, it does not contain info on when it worth enabling. From this point of view it seems like if i have 8CPU server an a NIC with 8000 ints/sec when i enable polling with HZ=1000 i get about 30 ints/sec from NIC about 16000 ints from NIC So, we were at 8000 ints a second and now we are at 16000 ints/second.

Re: device polling and weird timer interrupt count from vmstat
3) Is timer int really generated on each cpu? Am i really wasting cpu time on ~4000 ints per second? 4000 ints per second is rather nothing on any modern CPU. Have a look at the top(1) display of an otherwise idle system. The %interrupt column should be zero, even if it's processing 4000 timer interrupts per second. As far as I know, the cpu timer interrupt handler is very light- weight. Thank you for the answer. My convern is that with 4 CPUs i get 8000 ints/second. While em generates only about 200 ints/second. As i undertand not all int handlers are the same. Some are heavy and some are light on CPU. So, the question is what is better (better=less CPU time): 8000 ints/sec from timer or 200 ints/sec from NIC? -- Regards, Artem ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

As I wrote, run top(1) while the system is idle, so only the cpu timer interrupts are active. If the %interrupt column is zero most of the time, then there is nothing to worry about at all. However, if you have a constant non-zero %interrupt value, you might consider lowering HZ, and you might reconsider whether polling really has advantages in your situation. Do you have reasons to believe so? Remember that the main purpose of polling is to improve interactivity under very high network load. If you're not in such a situation, then polling probably doesn't buy you much. Well, problem with top is that on dual 3GHZ box it alsway s shows 0% load when not loaded with real traffic (web traffic) no matter if it is polling of int handling. And when loaded with real traffic web server eat a lot more cpu power then traffic handling, so, no separate measurement of traffic cpu load is possible. But i think it is possible to simulate this kind of load, need to think about it. Also, when it comes to public web server i can never be secure enough and crazy load of traffic can come any time from DDOS attack which can bring down any box. So, for public web server it is a matter of security and managebility to have server interactive even on high traffic load.

A little story of failed raid5 (3ware 8000 series)
Hello! Here is the newest story of mine about how one should never use raid5. Controller is 8xxx-4LP. I have a simple 360GB raid5 with 4 drives since 2004. Only about a year ago i realized how much speed i have wasted be saving lousy 120GB. I should have choosen bigger driver and setup two mirrors instead. But that's no the point. A week ago one driver just totally failed. It fell out of the unit and when i tried to rebuild the unit it failed. It seemed like the driver electronis failed. ANyhow, i have found newest 160gb seagate driver for replacement (twice as thin, very nicely done electornics on it). A day ago at 11 am i have turn off the server, pull out the old driver, installed a new one, turned of the server and started rebuild in an hour from remote location via web interface. After about 5 minuted the machine became unresponsive. Tried rebooting - nothing. I went to the machine and fingure out, that rebuild failed (0%) and some data cannot be read because of bad sectors. Well, hell, i thoght. Maybe i could tell teh controller to ignore all the errors and just some rebuilding and the figure out which driver failed, replace it, rebuild again and restore corrupted data from backup. Noway, controller said. - i cannot make it ignore read errors - i cannot figure out which driver has bad sectors (maybe someone know it?) But i don't understand how and why it happened. ONly 6 hours ago (a night before) all those files were backed up fine w/o any read error. And now, right after replacing the driver and starting rebuild it said that there are bad sectors all over those file. How come? Well. Since we have a buch of full and inceremnetal paraoid backups no data was lost and we are in process of recovering. However, i simply imaged what would happed if one more driver completelly failed. That would mean that we have lost all data, since any of the disk which left do not contain any readable copy of one data (unlink mirror, for example). So, we are migrating to mirror config with huge disks. I am thinking about raid10 for more perfomance. It seems a lot more safe, since if any pair of disks failed the data is still readable and even if all disks have bad block the data can be easily recovered by fairly simply script from the couterpart. But the problem, however, So, no raid5 or even raid 6 for me any more. Never! -- Regards, Artem ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Why would you power cycle a RAID 5 array with a failed drive? That's like the biggest no-no that there is. When you lose a drive on a RAID 5 array, you are vulnerable until a replacement drive is configured and the array is rebuilt. Any high risk operations during that time would be foolhardy. Um.. it is because i did not have a map of hot swap baskets to conroller ports and i needed to check every driver basket to understand which port it sits on. I have no choise, i think. So, no raid5 or even raid 6 for me any more. Never! Since RAID6 would have saved you from what presumably was a drive failure before a rebuild could be done, it's hard to understand why you would say this is a reason to avoid RAID 6. Perhaps you would do better to understand your failure and avoid the causes of the failure rather than avoiding the things you happened to be using at the time of the failure. If you get food poisoning while wearing a blue shirt, the solution is not to avoid blue shirts in the future. Read the post before. I still don't known which driver has the bad sectors. And it is very posible that EACH driver has them. RAID6 would not help then. -- Artem ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: When inode change time changes?
Oliver Fromme wrote: Artem Kuchin [EMAIL PROTECTED] wrote: I use gtar (gtar because it has incremental backups, and tar does not) You _can_ use BSD tar for incremental backups. I do that every day. Yes, but that's not real incremental backup because if you restore data you'll get a bunch of files that were deleted along the way. gtar stores full file list and actually deleted the deleted files when restoring. And i have excessively many of such created and deleted files and i need only current ones. So tar is of no use for me. Also, i use inode time because i only need files which really have been changed. For example, i you restore a file from a month ago it will have a date which is a month ago. Then that backup is destroyed but this file would not be backed up because the date is too much in the past. So, we loose the file. If i used inode change time the file will be backup in any case. However, some stupid programs like mysql or qmail seem to touch files so, for example, all mail message and databases are backed up every time. And this sucks. So, when backing up these files i need to use file modification time and it is suitable here, since these file are never managed by human, only by daemon and old file eather go away (like in email) or change its mod time (like in mysql). What is still do not understand is what time gtar uses for --newer option. Man page says: --newer dateOnly store files with creation time newer than date. This is simply not true.

How to test locale in C? All my tests fail.
Maybe it is the wrong list, but maybe someone can quickly
help me out.
I have a very stupid problem. I cannot convert to upper
or lower case using manually set locale (setlocale(..)).
A very simple program:
#include locale.h
#include errno.h
#include ctype.h
main(){
char *b=setlocale(LC_CTYPE, ru_RU.CP1251);
if (!b){
printf(FAILED! %d\n,errno);
}
else {
printf(OK: %s %d\n,b,errno);
printf(IS UPPER й: %d\n,isupper('й'));
printf(IS UPPER Й: %d\n,isupper('Й'));
printf(IS LOWER й: %d\n,islower('й'));
printf(IS LOWER Й: %d\n,islower('Й'));
printf(LOCALE %s\n,setlocale(LC_CTYPE,NULL));
printf(1: TO UPPER %c TO LOWER %c\n,toupper('ж'),tolower('Ж'));
printf(1-0: TO UPPER %c TO LOWER %c\n,toupper('Я'),tolower('я'));
printf(2: TO UPPER %c TO LOWER %c\n,toupper('r'),tolower('R'));
}
}
Output is always:
OK: ru_RU.CP1251 0
IS UPPER й: 0
IS UPPER Й: 0
IS LOWER й: 0
IS LOWER Й: 0
LOCALE ru_RU.CP1251
1: TO UPPER ж TO LOWER Ж
1-0: TO UPPER Я TO LOWER я
2: TO UPPER R TO LOWER r
й,ж,я - is lower case leters and
Й,Ж,Я - is upper case
As you see, it simply does not work at all.
It seems like the locale is C but as you see

Right. that why i first
call
setlocale(LC_CTYPE, ru_RU.CP1251);
to set locale
and the call
setlocale(LC_CTYPE,NULL);
to check what locale is currently set.
I tried without call setlocale(LC_CTYPE,NULL);
- no difference.

That's a common pitfall. Chars are signed by default on
FreeBSD, and the isupper() etc. function take an int type
argument. That means that characters = 128 end up as
negative numbers, so they fail all isupper() and islower()
checks, and toupper()/tolower() don't touch them at all.
The solution is to typecast the constants to unsigned char
explicitly, like this: isupper((unsigned char) '?') etc.
Your program will work fine then.
My stupid. I should've noticed that. Thank you very much!

Broken locale after upgrade to 6-STABEL from 5-STABLE
Recently i figured out that all locales stopped working
properly on some of my 6-STABLE servers and in all jails
on them.
These server diffeer from others (on which locale work)
in that they were upgraded to 6-STABLE directly from
5.3-STABLE.
Test was easy:
#!/usr/bin/perl
use POSIX qw(locale_h);
use locale;
setlocale(LC_ALL, 'ru_RU.CP1251') || warn LOCALE: $!\n;
print lc(РУЧКАручкаABCabc\n).\n;
(the string is partially in RUssia, so you might not
be able to see correctly, but that is not the point).
After an hour of figuring out why it does not work
i figureed that it was because of
/lib/libc.so.5
I chflaged it, deleted it and made a link to
libc.so.6
After that setlocale in perl worked fine.
However, on another server, where setlocale worked
and works fine this libc.so.5 also present and causes
no problems.
What i don't understand, is how the appropriate 'so'
is selected? How freebsd known which so to load
this
libc.so.5
or this
libc.so.6
?
where it is specified?
Another question, is why setlocale in C
says that locale is set fine.
A simple proggie:
#include locale.h
#include errno.h
#include ctype.h
main(){
char *b=setlocale(LC_ALL, ru_RU.CP1251);
if (!b){
printf(FAILED! %d\n,errno);
}
else {
printf(OK: %s %d\n,b,errno);
printf(LOCALE %s\n,setlocale(LC_CTYPE,NULL));
printf(1: TO UPPER %c TO LOWER %c\n,toupper('я'),tolower('Я'));
printf(1-0: TO UPPER %c TO LOWER %c\n,toupper('Я'),tolower('я'));
printf(2: TO UPPER %c TO LOWER %c\n,toupper('r'),tolower('R'));
}
}
Does not work even when locales work on perl (toupper does not
return an upper letter for russia, but works with latin r, same
with tolower).
Am i missing something?

GIANT LOCKED raid driver
We use 3ware cards (twe driver) on most of our server.

Does anyone know a good raid controller (raid-5 not really needed, mirror is enough) whose driver is not giant locked?

Migrating from x86 (32) to amd64
Maybe someone could help me. I have a machine with 4GB of RAM 128MB of which is wasted and i really need 2 gigs more. This is a heavy duty production server with a lot of jails and custom scripts, etc.. and i am afraid i cannot reinstall all from scratch. Furthermore it is located in the data center away from the office and i simply cannot spend whoel day there, but 2-4 hours would be ok.

What's the basis for your suspicion? My memory might play tricks on me, but i think I remember that i tried to upgrade from 4.1 to 5.3 longtime ago and it did not work. I had to up to 5.0 and the to 5.3. But that might be just some weird client install (i did not install freebsd on that box originally). The world just did not compile.

AFAIK nobody has lived to tell the tale (or at least I didn't see any followups from people who claimed they'd try it). In any case it would be better to migrate it via binary reinstall (the same as installing from scratch, using the boot CD...). Damn it. Then i guess i need to do some experimenting myself. Theoretically, what would be the procedure? Any recomendations? Try using PAE, but read up on possible problems. No, just not PAE.

What's the matter?! If you use dd on the raw device (meaning no UFS/VFS) there is no read-ahead. This means that the following DD-command will give lower STR read than the second: no read-ahead: dd if=/dev/mirror/data of=/dev/null bs=1m count=1000 read-ahead and multiple I/O queue depth: dd if=/mounted/mirror/volume of=/dev/null bs=1m count=1000 You can test read STR best with bonnie (see /usr/ports/benchmarks/bonnie); or just with DD on a mounted volume. You should mount with -o noatime to avoid useless writes during reading, or use soft updates to prevent meta data from taking it's toll on I/O performance. Totall disagree. On the following reasons: 1) Read ahead is simply useless when stream-reading (sequential) 1GB of data 2) atime is NOT updated when using dd on any device, atime is related to file/inode operations which are not performed by dd 3) soft update are also useless (no bad, no good) for long sequential read basically, long sequatial reads/write ignore anything but real drive speed (plate on the spindle) if they are performed long enough.

Re: Boot prompt for Intel AMT
I hope some people will understand what i am talking about, because the technology, i think, is not very popular, but can come VERY handy. Intel AMT Serial over LAN (SOL, why is it called 'over LAN' if it is really 'OVER IP'?) allows to boot into BIOS of a remote machine and even, as seen in their demo, can be used to control MS DOS prompt. well because it isnt using IP, besides SOIP is uninspiring :) Wait.. how so? I was sure that the whose SOL (IPMI) protocal is running over IP and i can REMOTELY (e.g. from anoth planet with IP connection) access the machine in the data center. If i can do such thing, then it DOES run over IP eventually. Isn't it? Anyway, nobody said anothing about getting freebsd boot prompt over SOL. My guess, that this is THE MOST usefull usage of SOL for remote upgrades. I understand that this is not as simple as sending data to UART. THis is must be done explicitely in the boot loader, i thinks.

Hello! I hope some people will understand what i am talking about, because the technology, i think, is not very popular, but can come VERY handy. Intel AMT Serial over LAN (SOL, why is it called 'over LAN' if it is really 'OVER IP'?) allows to boot into BIOS of a remote machine and even, as seen in their demo, can be used to control MS DOS prompt. However, i tried it and did not see any boot prompt over SOL connection. As i understand it does not use bios for input/output and therefore data is not sent/received over SOL connection. Thisis a pitty because of boot prompt would work over SOL then remote source upgrade would be much plainless and less risky than now. For example, i could just book old kernel if something goes wrong. Is there a way to make boot prompt work over SOL?

The inability to boot because one disk got hosed is Bad News (tm). A decent UPS can help here. No, i can't. I have seen UPS (even APC) fail in some cases. Computers got frozen. Also, i've seen many cases when power failes for more than 4 hours and nobody want to buy UPS which hold 4 hours of power for a dual xeon with 5 hdds. It depends on your exact situation, I was just pointing out that SW RAID doesn't cover all the bases HW RAID does. If the disk is dead then the BIOS will skip it and the system should boot normally (I've tested this by pulling a disk since I didn't have a suitable dead disk to hand). A hard error in the 2nd stage boot loader, ficl or the kernel is definitely the worst case - I agree that this is very difficult for software raid to recover from. No, BIOS does not always do it. If HDD REALLY fails (chips fried or something is really messy) the BIOS often just become frozen and never boots. I have seen it too. I've seen many things, you know :)) Note that even with hardware raid, there are still lots of failure points. The least reliable parts of a current computer are the CPU and PSU fans, not the disks. That is why RAID controller MUST be w/o fans and there must be MANY fans inside server case and there MUST constant temperature monitoring with SMS, EMAIL, ICQ messages on alarams. -- Artem ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

What is a good choice of sata-ii raid controller for freebsd?
Hello! I need a raid controller for FBSD 6.2 which has the following options 1) Full SATA-II support 2) Good rperfomance (over 50MB read, over 30 write) in mirror mode 3) No weird problems with freebSD (like with SRCS16) 4) Utility to monitor status of raids (command line or web) 5) Utility to rebuild, repair, manager arrays in OS 6) Preferably Intel I know, 3ware has such good stuff, but those controller are not certified for internet services in here (russia). So, i am pretty much limited to Intel controllers. Is there intel controller which satisfied all the 1-6 conditions?

I did that and then tried to run perl. Got segmantaion fault. Ignored that and tried to copy port tree and then i found out that some files are damanged and connot be read. Also, directoried could not be deleted because it is not empty, but when i do ls in that dir it IS empty. weird. Booted single user, did fsck - found a buch of errors, many softupdate inconsistencies. Fixed them. Rebooted (still in PAE). Run buildworld and copy ports tree at the same time. AFter 10 minutes again the same errors. Built a kernel without PAE, installed, rebooted in single user, fixed all filesystems, booted multiuser, run buildworld and copy of ports tree. Everything is okay. Did it many times. Still everything is ok. Is it something bad about amr driver working under PAE? Also, with and after running in PAE (i mean, run PAE kernel, then install normal kernel and run it) the kernel compains like this _vfs_done(): amrd0 [WRITE(offset=8192, length=1536)] error = 5 (no other message before or aftrer this, disks are fully okay becuase dd works like a charm) Also, i did a simple thing dd if=/dev/amrd0 of=/dev/null bs=1M (tried 2m, 5m, 512k) The throughoutput is about 29MB/sec w/o PAE and 27MB/sec with PAE Did the same on a very old DUal Pentium III with 3Ware 7 with RAID-5 array and older harddrives.

Unfortunately I don't know of any solution. A (tedious) workaround (in case repeated attempts always fail for you), is to install a minimal system off an earlier version of FreeBSD and run the installer off the installed system - or just src upgrade to the version you want. I found that the 4.x, 5.0, 5.1 and 5.2 cd's all worked fine - but 5.3 onwards and 6.x would register dump. There is a better workaround which i used. A simple start of installer from 4 floppies. Then install the whole system from CD-ROM. It does work but insolved copying of floppy images onto the disks. However is it a very annoying problem which i have been encountering since 5.0-RELEASE. The bootloader failed when trying to load installed from CD-ROM on pretty much every PIII and old Celeron pc which i tried. (it is about 6 machines by now).

Quotas inside jails
Sometime ago and have setup 5.3-STABLE box with quotas for jailed users. At that time quotas did not work inside jails, so i just created some group on host machine and group with the same ID inside jail and then put a quota upon that group on the host box. That was quotas are observed. However, user iside jail cannot check their quota this way. Do quotas work now (as of 6.1-STABLE) inside jails correctly?

Re: SATA vs SCSI ...
Marc G. Fournier [EMAIL PROTECTED] wrote: looking at the specs between two cards, the SATA card(s) seem to rate ~100-150MB/s on each channel (if I'm reading right), with both the 3Ware and ICP cards having 4 individual channels ... looking at the SCSI cards, they are rated at 320MB/s, but that is total for the SCSI bus itself, right? So, if I have three drives on a SCSI bus, each 'maxing out evenly', I'd be cap'd at about the same 100MB/s per drive, no? In fact, looking at the SATA 2.x specs, each chanell there is rated at 300MB/s, which, again, if I could 'max out evenly', could seriously blow away the SCSI bus itself ... *If* I'm reading this right ... ? For the last 6 month i really think that if you don't need something high-end scsi then you should go for SATA. There are test on sites such as Tom's hardware guide and ixbt.com. They show then on sequrncial read there is no difference between scsi and sata. Acatuallty, modern hdds use the same mechanics for sata and scsi versions of them. The brains (electronics) on the hdds are different of course. However, when it comes to random read/writes scsi wins because of command queueing. This was an issue until recently, Recently SATA with NCQ became widly available. Test show that some of those SATA disks with NCW ***WIN*** over scsi 320. The test envolve artificialy random read/write tests as well as real application benchmarking. I din't rememeber where excatly i saw the tests on those site, but you could search. So, my opinion, workstation never needs SCSI and every server MUST be on mirror or RAID5 and there you should use SATA with NCQ drivers unless, your applicaton is really weird and needs something extremely speedy. Then, however, you could go for RAID 0+1 and get perfomance that SCSI will never get you. -- Regards, Artem Kuchin IT Legion Ltd.

To prevent that kind of thing you need to use 802.1x authentication or maybe even PPPoE. Um.. I just have read tutorial about PPPoE and did not find anything about matching IP and MAC addresses. So, if i use PPPoE i still need to do static ARP (i did not undestrand, how i somebody can match mac and ip with static arp except that he actually get the physical NIC from somebody's computer). Also, as i see, users on PPPoE can login from any computer and get their IP address.It will not work because of static arp, but still, there are getting their address. And the last thing, if i am to migrate to PPPoE this basically means i will need to give up DHCP, because PPP will serve IPs, not DHCP. Right? And now the theory question. While i am running pppoe server on some ethernet interface what disallows any user to use that interface as a ip gateway without any pppoe? Just assigned themselves an ip, ignoring pppoe and using the server as a gateway.

I've just committed the fix as subr_witness.c:1.187 in HEAD, and subr_witness.c:1.178.2.4 in RELENG_5. Please let me know if this doesn't fix the problem for you. It fixed the problem. I am actually stuggling with unpredictable weird lock ups, when the host can be pinged but i cannot connect via ssh/telnet or httpd or anything else. It happens w/o any visible reason. I am running several jails with mysql and apache in each and canot make the whole system stable yet. This is typically a sign of one of two problems: - The system is live locked due to very high load, so the ithread, netisrs, etc, in the kernel run fine, but user processes don't get a chance to run. - The system is dead locked due to user space processes getting wedged on common locks, but the kernel ithreads and netisrs can keep on responding. I generally assume that it's a deadlock as opposed to a live lock. I'd compile a kernel with DDB, KDB, WITNESS, and BREAK_TO_DEBUGGER. When the system appears to wedge, break into the debugger using a console or serial break (FYI: serial break is more reliable, and you get the benefit of being able to easily copy and paste debugging output using the serial console for DDB). Use show alllocks and show lockedvnods to examine most of the system's locking state. Changes are, either all the interesting processes are stacked up on VFS or VM locks, since those kinds of deadlocks produce the exact symptoms you describe: ping works fine because it only hits the netisr, but when you open TCP connections, the sshd (etc) block on VM or VFS locks attempting to fork new children or access a file in the file system name space. At first, the TCP connections will establish but there will be no application data; after a bit, they will not even return a SYN/ACK because the listen queue for the listen socket has filled. Well, i cvsed and reconpiled the kernel with WITNESS, INVARINATS, turned off adaptive giant and got a lock today at 7 am. Since the server is remotely controlled i took my digital camera because i cannot connect serial console to it and went to the server. I expetced to see some special message about something going wrong, break into debugger (CTRL+ALT+ESC) and to take some pictures of dumps of console. But, i saw nothing. The lasrt message on th screen was about ssh loging last evening and the last message in /var/log/all.log was about entropy save from cron. I could not break into debugger usinmg CTRL-ALT+ESC. I did nothing. So, it looked like a hard lock. At this point i would like to tell the whole story. We bought this server in may 2004 and decided to extemsively test the hardware while there were not 5.3. We actually expected it around august. SO, we installed 5-CURRENT and ran high load tests (cpu, memory, disk storage, network) from /usr/ports/benchmark at the same time and one-by-one several weeks. There were not a glitch. After that we turned it off and waited for RELEASE. RELEASE has come and we begun to setup the servre as it should work. As the server's primary mission is to host a buch of site we decided to setup jails for each site, So we did in december and put the server on prividers co-location severals kilometer away from the office. Next day the server locked up. We were surprised but just rebooted it, It locked up the next day gain. We cvsupped and rebuild the system and the jails. The server locked up the next day. During the new year break i have figureed that if there are more that one jail running the server locks withun 24 hours with very hight probablity and within 48 hours with 100% probability. I wrote into freebsd-stable about it. You have asked for debugger dump (pcpu, list of lock, e.t.c). I could not do it at that time, so, i did not reply and just cvsupped in the beginning of january and rebuilt the system and the jails again. Magically, after that i could run 5 jails (did not tried more) for over a week and i already decided that the bug was fixed and I could host the site. Alas, the next glitch did not wait to long. After a few more days i saw a srange situatuon - i could not connect to server using SSH. SSH replied about auth key or something like that. I rebootied the system and ssh worked fine. Still have no idea what that was, but i setuo IPFIREWALL and a telnet server for accept connection only from one ip address, so, if ssh fails I could use telnet. After that i moved a real site with perl scripts, 1GB database, mail account (using qmail+vpopmail) into one of the jails and the next day got the next problem: I could ping server, but could

Server locks up if more than one jail in running
I have a very bad problem. I need to seetup large number of jails (about 100) to do virtual hosting and i am doing it on 5.3-STABLE (not 5.3-RELEASE, i mean -STABLE which is cvsupped). So, when i setup one jail - everything runs fine for many days. If i setup one more jail or 3 or more - server locks up (freezes, hangs, becomes totally unsresponsive) within 48 hours. Sometime it runs only a couple hours, sometimes almost a couple of days. So, to diagnose the problem i setup a cron process which saves a lot of system statistics every minutes. The last working minute stats are included below as well as basic system configuration. Jails are complete distributions, but very basic services are running: cron, sshd. adjtimezone is disabled. All other records on /etc/crontab are left just like in distro. I really need help with this problem because i canno migrate to 5.3 because of it. And i really need 5.3 because of some new features.
