In particular, the daily periodic tasks that run the various 'find' were one of the things I noticed (although we run numerous tasks out of cron)... If something is blocking the filesystem and causing find (and possibly other processes) to become stuck, these would just keep mounting up until it all falls over (with numerous maxproc exceeded etc errors). These are on machines without NFS, but the symptoms are very very similar.. NWFS and SMBFS are commonly used on a number of the machines I've seen the problem on, which may be relevant -- perhaps it affects more than just NFS? I may experiment with building up a test server locally and trying to reproduce similar loads to see if I can trigger the problem in-house.. at least that way I can hook up a serial console and get some more detailed information...

Re: Intel ICH7R RAID controller working on 6.1/STABLE?

Think about what happens if one of your disks dies. Sure, the machine will carry on running. With an on-board controller there are two problems: i) How do you get notified that a disk has died ii) How do you replace the drive (i) you'ld likely only find out about at reboot time, or by noticing a change in the pattern of blinken-lights on the machine. (Don't laugh -- it happens) (ii) is not just about having to power off the machine and swap out the hardware: it's not uncommon for on-board RAID-1 setups to be unable to rebuild a mirror by duplicating the good disk onto the replacement one. That means blowing everything away and recovering from backup. By which time you've had so much downtime that you might as well not have bothered with RAID in the first place. The advantage of a good RAID controller -- like one of the 3ware cards -- or of gmirror is that combined with hot-swap disk (and pretty much all SATA drives nowadays have hot-swap capability; you just need to find a chassis with the right sort of drive bays) then you can take out the dead disk, replace it with a good one and rebuild the array *without taking the machine down*. gmirror will alert you to failures in the nightly e-mail if you enable the 406.status-gmirror periodic script. Similarly a good hardware RAID controller will have a system level control application to let you interface with the card from the OS level, and it will have some mechanism for alerting the admin to problems.

Hey Fabian, To you have pf running? If so can you turn it off for a bit a see if you still crash. On my box I was getting all sorts of witness kbd backtraces on pf and since turning pf off (maybe a week ago), haven't crashed yet. Going to let it keep running unmetered for another 2 weeks and see if I crash or not. -Peter ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

burncd blank and format problems
Sorry to have to bring this up again, seems like it was an issue 4 years ago, but I don't know if it's really resolved. If I do: #burncd -f /dev/acd0 blank then burncd will sleep forever. (I have to Ctrl-C for it to exit) It doesn't really hang, but please read this: http://www.freebsd.org/cgi/query-pr.cgi?pr=44803 (I looked at the source code, the only thing I could figure that CDRIOCPROGRESS is ALWAYS returning 0. Inside a while(1), that will never break; Same results with erase instead of blank. On that pr (44803), user says blank worked, however, even when I Ctl-C and break after a while, any data that I write on the disk is invalid: I mean that if I copy it, it will not pass diff. Now this could be a problem with my DRD-RW device, but all of the other ports work with it. So is this my configuration problem?

asus wl 530-g router
Hi all! I'd like to know if someone has experience with this router. The signal comes from cable modem, to wan port. It has 4 lan ethernets and wireless G. The chip is (probably) Marwell, os linux embeded. Internet provider offers dhcp dynamic address. I would use static IPs in lan. Has nat and some kind of firewall. Question? Should I take this? Does it pass through telnet, ssh, ping (from inside out)? How nice works wi-fi component?
