My system is locks up when an application attempts to copy a large file to an nfs mount. The system becomes unresponsive to the point that I cannot even reboot via the command line over SSH. For example, when soundKonverter copies an ogg file from /tmp to /home/music (nfs share).

[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
I hade some frezes as well with Ubuntu 9.10 64-Bit and 10.04 The problem was as followed: As I started to download (in my case it was by JDownloader) after a while the whole system freezes. I checked My RAMs and one seemed to be faulty but as I changed it to a new one the problem was still up. We I used one single 1024MB and it worked perfect (each of the stand alone) As soon I entered the second one the freezing problem is back. I've seen at some forums threads, they had problems with the same wireless card as I use (Netgear WN311B). For addition the same Netgear card was running fine on an other PC with Ubuntu 32-Bit I was using the Broadcom driver by the proprietary drivers. Now I changed the Wireless-card to a plug and Play (out of the box support) and all the freezing problems are gone. I don't think the card is faulty, Probably something with the RAM addresses? I have no idea, but the fault can be rebuilt.

[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
I had experienced this problem (system becomes hardlocked during heavy network transfer) on Toshiba Satellite L4 laptop in Jaunty and Karmic. Later it turned out there was a hardware fault in one of on-board inverters. Just have my motherboard replaced and the issue disappeared completely! No more system hardlocks, neither error messages in system logs for several days. Conclusion: while reporting software failure one has to be cautious about the conditions of hardware. It even worth it to ask a specialist when possible. These faults are not easily identifiable, and manifestation can be contr-intuitive. -- Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes. https://bugs.launchpad.net/bugs/147464 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Well in my case I don't think it is a hardware issue. I am also using windows7 alongside and I use utorrent for almost 3 days in a row and it works fine without any hang, but in Ubuntu 9.10 it was an issue with download speed more than 500 kbps. Right now in Lucid, I am still to encounter this problem; it works fine with speed up to 1.5 Mbps.

[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
Well, in my case there was (and still is) a hardware issue - due to flaws in design the PCI chip on a motherboard (not CPU neither graphic card!) has become overheated during prolonged heavy wireless transfer by additional heat dissipated in nearby on-board inverters. I have to fix the issue completely (I am very close to that) before testing my system again. -- Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes. https://bugs.launchpad.net/bugs/147464 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
Have being using Transmission (1.75 to 1.91) for over a year in Ubuntu 9.04 to 9.10 on my Toshiba Satellite L40 laptop connected to the Internet via built-in Atheros AR5007EG wireless card installed in mini- PCI. While using Transmission I discovered that downloading from large swarms at high speed resulted in regular system crash (kernel panic) within 30 min to 1 hour. Recently it turned out the issue is system- wide, i.e. any heavy network activity triggers system crash. My search through Linux support community made me think that a bug in Linux kernel which causes i/o stalls in some cases (seems has been fixed in kernel 2.6.32) could be responsible for it. Recently however I have found a hardware problem in my laptop. The PCI chip (not the CPU!) lacks proper cooling due to limitations in laptop design, mechanical defect in its radiator and partial blocking of ventilation slits by dust. After fixing mechanical problems my system has become rock stable. Still I was able to trigger system crash by heavy i/o activity - while downloading at ~2.5 MBits/s over wireless and transferring lots of data (~10MByte/s) via IEEE1394 PCMCIA card simultaneously and for a prolonged time providing that a temperature of cooling air is above 24 deg C. Problem solved. Conclusion: before reporting a software problem, it should be wise to check all your hardware carefully... -- Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes. https://bugs.launchpad.net/bugs/147464 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi I am also facing similar issues since, I am using Karmic 32 bit 2.6.31.19-Generic. The system freezes and nothing can be done except hard reboot. I have Intel 5150 WiMax card.

[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
Have being running Ubuntu (9.04 to 9.10) on Toshiba Satellite L40-139 laptop for about a year. Heavy network traffic systematically triggers a crash (either kernel panic or segmentation fault). Among applications that have triggered system crash are: firefox (all versions since 3.2.3), system update manager, a Java-based application downloading via http/ftp as well as bittorrent client and wget. Usually the problem appears within 20-30 min while downloading at speed of 150kBytes/s or more. Just before the moment of crash, tons of messages like: Feb 3 02:30:04 kovalev-home kernel: [35474.511460] recvmsg bug: copied BFA5DAF9 seq BFA5E0A1 fill up system logs on pair with application-related warning. Sometimes (fifty-fifty) there is no immediate crash after warnings have appeared, but part of downloaded data have become corrupt. The problem has been observed first with kernel 2.6.28-13 but still persists through current 2.6.31-19, all have been installed from official Ubuntu repositories. Network connection is via Atheros AR5007eg wireless (reported as AR5001 by ath5k).

I think I spoke too early when I said that this was fixed in Intrepid x86_64 I think I am seeing this again. I am downloading a file from an ftp site with Firefox and my system keeps freezing for approx 5-10 secs at a time every couple of minutes. The Windows all go dark and then come back to alive again which is what I was seeing before. The download is only running at 100KB/s sois only using minimal bandwidth on my corporate 30MB/s Internet connection.. My laptop is plugged into a 1GB network port at the core of our 3Com network. I declare this still a problem - but the occurrence is different to what I was suffering before: it is a lot less and the system seems to be able to un-stick itself rather than requiring a hard reset. Still Bl**dy frustrating though - my system has locked up about 10 times whilst writing this post. Almost unusable!!

[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
I have had this same issue since 7.10, currently on 8.04 and after almost a year finally figured out that it always seems to hard lock when I've got a ton of torrent activity. The up/down speed it locks on is always different, so I'm thinking it has to do with the number of connections present at the time and not the about of bandwidth being used. To be sure I have tested every piece of hardware, replacing my NIC (no effect, except I upgraded so now I get even better speeds) and replaced my PSU due to a slight fluctuation in one of the 5v rails (within limits, but barely) which also had no effect. CPU, heat, RAM, HDs, etc all tested fine. So this is definitely a Linux/Ubuntu issue. My issues are exactly as above, seemingly random hard locks requiring the use of the reset/power button. I cannot confirm cases of num lock/caps lock/etc lights blinking as my wireless keyboard doesn't have those lights. Please fix this issue, it should be of a relatively high priority due to the nature of the issue and the possible public (read non-Linux users whom wish to try Ubuntu) assumptions that Ubuntu is not a stable OS. I personally have fiber at home, and up until now (when I realized where the issue is) I would happily leave any and all torrents running until these was not a single peer left, having a constant 3-5Mbps (and higher) upload going. I've tried other torrent clients (I prefer Azureus) with the same resulting hard locks. -- Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes. https://bugs.launchpad.net/bugs/147464 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

My connection is also a WIRED connection. To further clarify, I DO NOT experience a system lock-up, NOR do I see the blinking caps lock, scroll lock, num lock lights. What I experience is total network absence; as if you'd unplugged the machine from the switch. If I do a "sudo ifconfig eth1 down" and then a "sudo ifconfig eth1 up" from the terminal, the network comes back to life.

[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
Um, no... the problem persists. My machine is a single AMD Athlon Processor (32 bit of course!). It was happening with Hardy Heron, and before that with Gutsy Gibbon, and now of course with yesterday's upgrade to Intrepid Ibex. The kernel I'm running is (from uname -a): Linux MythTVServer 2.6.27-7-generic #1 SMP Tue Nov 4 19:33:20 UTC 2008 i686 GNU/Linux My machine drops the network connection to the world when transferring large files, I can make it happen in 2 or 3 seconds by trying to copy a large number of mp3s from a Windows share to the Ubunutu server through Samba. It can also happen, as a user stated above, by lots of network connections of little bandwidth when using MythTV. (This failure's occurance is unpredictable, and the server can last for weeks with no problems before the remote frontend complains about not seeing the backend anymore.) I am using quality Netgear pro Gigabit switches. (The nice metal ones.) I've swapped network cards (Linksys PCI Gigabit cards) and used the onboard 100 MB VIA card as well. None of this eliminates the bug. I've also sucessfully used the same network card on a x86_64 version of Ubuntu on another server with no problems! I've also used another x86_64 server with a built in network card with no problems. The only things that are specific to my lock up is the motherboard/CPU... perhaps could it be the PCI bus controller? What about the BIOS's ACPI control? The machine has 6 hard drives with one PCI IDE soft-RAID controller, the onboard IDE controller, and 2 Hauppauge PVR350 PCI video capture cards. The results of "cat /proc/interrupts" shows the eth1 (Linksys Gigabit) card is sharing Interrupt 16 with one of the ivtv devices... but both work. There are no errors in the ring buffer (/bin/dmesg) or the syslog. As this makes me want to hit my computer with a BFH, let me know what I can do to help track this down. -- Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes. https://bugs.launchpad.net/bugs/147464 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I suffered from this bug under both nics (e1000 and iwl3945), on both reproducable, sometimes it takes 5 mins, sometimes 8 hours but I didnt download one bigger file (>1G) over bittorrent without a freeze. It happened sometimes that bittorrent ran for some hours, without an user, and the freeze happened just when I startet firefox and began surfing. But I stopped downloading using bittorrent for some weeks and no freeze happened for that time, and I produced some heavy network traffic (copied 150GB with rsync over 100mbit ethernet more than once). -- Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes. https://bugs.launchpad.net/bugs/147464 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
I have only experienced this bug when connecting using 802.11n. Otoh, my system doesn't completely lock up, just the network interface stops responding. The bug I am describing does sound a bit different from this one... I'm using a broadcom wireless adapter with the latest (1.53?) ndiswrapper and a driver that works on windoze. I believe what I'm experiencing is a kernel bug though because once the network interface goes down nothing short of a reboot will get it working again. I guess I should mention that I'm on 32bit hoary, but I've had the same exact experience with 64bit, and on both fiesty and gutsy on this particular machine, and using several drivers and several versions of ndiswrapper. My workaround is to just only connect using 802.11g or b and everything works just peachy (if not a little slower than I'd like).

I encountered this bug on my (non x64) Thinkpad using a 3G/GPRS modem. As I stated then, "Updating the kernel from 2.6.22-14-generic to 2.6.23.9 seems to have eliminated this bug from my system."

[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
I've tried using ubuntu 8.04 32bit and the problem is exactly the same there. Total system hang when downloading large files. I've now installed an ubuntu 7.04 and the exact problem doesn't seem to reproduce itself. I've succesfully downloaded a large number of updates(about 400MB if i have to guess, didn't check how much exactly) at 493KBps without hang under the following kernel: Linux lx-ub710 2.6.22-14-generic #1 SMP Sun Oct 14 23:05:12 GMT 2007 i686 GNU/Linux I made sure not to reboot to give me some change to test if downloading a torrent would not reproduce the problem. And although my network connection stops functioning properly with a message to submit a bug to rt2x00.serialmonkey, the pc doesn't hang in itself, which was by far the most troubling aspect. I hope this is another problem I'm encountering now, one that can be solved. Although I would love to help fix this problem, the fact that it seems to be ongoing since november 2007 doesn't seem promising and I need this new machine to be productive. -- Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes. https://bugs.launchpad.net/bugs/147464 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
I too have this problem with 8.04 on a Thinkpad T60(8744-5BU). It started about two to four months ago. I wish I remembered exactly when. I did not do any kind of bug report then as I had to take the time to eliminate the possibility that it was due to the bleeding-edge drivers I generally use(madwifi and radeonhd). The symptoms of the lockup are: * NO blinking caps light * a total system freeze, * unresponsive to sysrq * If the hard disk was active at the time the disk light remains lit * nothing in the logs I tried using the distribution's radeon and fglrx x.org drivers, I completely disabled the madwifi drivers, and I tried running older Hardy beta kernels I had installed such as 2.6.24-12-generic but still experienced lockups. Then I noticed that the lockups seem to occur while the laptop is being backed up. I use BackupPC(rsync as the transfer protocol) to backup the laptop both at home and at work. The lockups happen 80% of the time during a backup at home and not at all at work. I disabled backups at home and it seemed to help. There were a few lockups that did happen so this may indicate it is a certain pattern of network activity rather than an application that causes it. Then I did some Bittorrent downloads using gnome-btdownload and had lockups quite consitently with that too.(I don't use Bittorrent at work so I can't really test to see if there is a network-specific issue here.) I then did some Bittorrent downloads using btdownload-curses from the console and not switching away from the console. No lockups. BUT, I found that after doing this(with a full or partial BT download) and switching back to the Gnome desktop the system would lock after a few minutes. Also interesting is that I recently did a long Bittorrent (gnome-btdownload) download from a slow seeder(1-5 KB/s. I know that is REAL slow, but it hardly matters when I leave the laptop on ovrenight) and did not have a lockup UNTIL the system experienced high network utilization.(MythTv I think) I have had only two lockups while running MythTv(viewing HD video) with its high network utilization.(one mentioned above) There have been a few lockups during regular web browsing and network utilization was low. Again, it does not always appear to be a matter of the amount of network utilization, but some other factor. I must also note that I am ALWAYS on the WIRED ethernet when these lockups happen. I wonder if there is an e1000 driver issue? Or an interaction between e1000 and some junk switches?(I've got a no-name 10/100 switch) I have not been able to obtain any metrics that would indicate a problem. I was monitoring the values in /proc/slabinfo and did see the number of active objects for "dentry" increase quite a bit during Bittorrent downloads and backups. But this is where everything is black magic to me. I can get you these numbers if you thinkg it will help. Running kernel 2.6.24-19-generic.

[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
I want to back up what "BongoMan" said above, in relation to the Marvell Yukon 88E8001 causing problems. Ever since I started using Ubuntu (I started at Gutsy Gibbon 7.10, currently on Hardy) I have had kernel panics (a complete system lockup / crash / freeze and blinking Caps lock and Scroll lock lights) whenever I ran torrent programmes like Azureus or Transmission and less often when I ran Firefox 2 or 3 and YouTube. Throughout that time I used the Marvell Yukon 88E8001 LAN adapter. The torrent programmes would run for 10 minutes to 2 hours and then kernel panic, Transmission was occasionally better than Azureus at staying stable for longer but eventually the system would panic. Like I say also watching videos on YouTube was a common source of crashes and occasionally just normal browsing - i.e. internet activity. Yesterday I remembered I had a second LAN port on my PC (an nVidia CK804 Gigabit adapter) and I decided to change over to it to see if things would improve and by gum they did. I have been able to run torrent (Azureus) straight for almost two days now without a hiccup. Unfortunately I can't say I am having the same problems in relation to picking up DHCP request or connection drops. My 88E8001 has never dropped once or failed to fulfill a DHCP request (i.e. receive a DHCP I.P.). Here is my hardware: - ASUS A8N-SLI Deluxe Motherboard - Marvell Yukon 88E8001 Gigabit LAN adapter (onboard) - nVidia CK804 Gigabit LAN adapter (onboard) - nForce4 chipset - AMD Athlon 3700+ San Diego - 1GB Corsair XMS4400 DDR RAM - nVidia 7800GTX PCI-E graphics card -- Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes. https://bugs.launchpad.net/bugs/147464 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
I confirm the bug. I can reproduce it by copying a directory of 8.5 GB from a mounted NFS drive to a local drive on my Compaq Pressario V6850ED. Or by downloading the directory with FTP. Even by copying it from the mounted NFS drive to the same mounted NFS drive(!). I can do so from 2 different servers (one AMD-64, one Pentium4). I can do it with Kubuntu 8.04 AMD64 as installed on the V6850ED. Or by running Kubuntu 8.04 I386 live from the CD. I use different physical locations on our network with different UTP cables. I tried many combinations (not all of them) and the result is always the same: At 3% to 55% in the copy process the V6850ED freezes with a blinking capslock light. However, if I replace the V6850E by a Compaq Pressario C760ED I can copy the same directory from the same mounted NFS drive without any problem. I tested this with Kubuntu 8.04 I386 as well as with Kubuntu 8.04 AMD64 installed. The C760ED seems a tropical machine that never freezes. The Compaq Pressario VG850ED has an AMD Turion 64 X2 TL60 processor @ 2GHz and 3072 MB DDR2 SDRAM. The Compaq Pressario C760 has an Intel Pentium T2370 dual core processor @ 1.73 GHz and 2048 MB DDR2 SDRAM.

Well, this hard lock is observed by us in *every* ubuntu kernel starting with feisty's 2.6.20 flavor. We observed hard locks on webservers and on our laptops. The common factor seems to be a large number of simultaneously opened TCP/IP connections either through the number of clients in the case of the web server of through a low-bandwidth internet connection (GPRS/UMTS) on the laptop.

[Bug 147464] Re: Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes.
Hello, I'm running the latest Hardy beta (kernel 2.6.24-16-generic) and I'm having this issue also. For me it happens when I do a large file transfer to either an SMB share or via FTP. It's hard to say whether it's the network or disk activity that triggers it. The system locks hard... a reset is necessary. It won't respond to the keyboard or network requests. Unfortunately the syslog doesn't give any useful information at the time of the freeze, though it does log the restart... Anyone have any tips on tracking down the cause? -- Heavy network activity (eg: torrent/nfs file transfers) causes Hard System Locks and/or Network Freezes. https://bugs.launchpad.net/bugs/147464 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

That's definitely good news. That means Hardy won't have a problem!

Updating the kernel from 2.6.22-14-generic to 2.6.23.9 seems to have eliminated this bug from my system.

This bug was nominated for Gutsy but does currently not qualify for a 7.10 stable release update (SRU) and the nomination is therefore declined. According the the SRU policy, the fix should already be deployed and tested in the current development version before an update to the stable releases will be considered. With 7.10 now released, that policy applies to this bug. See: https://wiki.ubuntu.com/StableReleaseUpdates . The bug is not being closed as work will continue on fixing it for the next release, Hardy Heron (8.04). If the state of this bug should change such that it qualifies for the SRU process, please contact the person who originally declined it and ask them to re-evaluate it.

I'm not having any trouble since kernel 2.6.23.8, 2.6.23.9, but since the bug doesn't appear very often on my system, it's not appropriate for testing and making any more or less reliable conclusions. Please update your kernel and test it On debian-based systems i'd update as follows: Download the sources from kernel.org and extract them as root: cd linux-2.6.23.9 cp /boot/config-2.6.22* .config #Copy the config of your current directory to the linux source directory and name it ".config" apt-get install kernel-package #Not sure if more is required make menuconfig #I think you can just exit after, if you don't want a configuration that is similar to your old one make-kpkg --initrd kernel_image make-kpkg --initrd kernel_headers #Required if you want to install proprietary graphics drivers and such later Now there should be 2 newly created deb-packages in the parent directory of the linux source directory.
