My server gets kernel panic every 7th day
Hi, i've had my server up for over a year now and it's been rock solid but for the latest weeks the server has rebooted evert Saturday at exact 04:19:57 because of a find command. I have no idea why and I've checked the cron log and I don't think any crontab is runned at that time. Not as far as I can see from the cron log. Anyway find makes the server get a kernel panic and it reboots. This is the fourth week in a row it happens and I've checked the hardware, no problems at all. I'm running 4.10-RELEASE-p5 so there is nothing newer to update to. Output from the message log: Dec 18 04:19:57 donnex /kernel: Dec 18 04:19:57 donnex /kernel: Dec 18 04:19:57 donnex /kernel: Fatal trap 12: page fault while in kernel mode Dec 18 04:19:57 donnex /kernel: fault virtual address = 0x4 Dec 18 04:19:57 donnex /kernel: fault code = supervisor read, page not present Dec 18 04:19:57 donnex /kernel: instruction pointer = 0x8:0xc01a35a3 Dec 18 04:19:57 donnex /kernel: stack pointer = 0x10:0xdde38e90 Dec 18 04:19:57 donnex /kernel: frame pointer = 0x10:0xdde38ea4 Dec 18 04:19:57 donnex /kernel: code segment= base 0x0, limit 0xf, type 0x1b Dec 18 04:19:57 donnex /kernel: = DPL 0, pres 1, def32 1, gran 1 Dec 18 04:19:57 donnex /kernel: processor eflags= interrupt enabled, resume, IOPL = 0 Dec 18 04:19:57 donnex /kernel: current process = 16533 (find) Dec 18 04:19:57 donnex /kernel: interrupt mask = none Dec 18 04:19:57 donnex /kernel: trap number = 12 Dec 18 04:19:57 donnex /kernel: panic: page fault Dec 18 04:19:57 donnex /kernel: Dec 18 04:19:57 donnex /kernel: syncing disks... 46 9 2 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Dec 18 04:19:57 donnex /kernel: giving up on 1 buffers Dec 18 04:19:57 donnex /kernel: Uptime: 6d16h7m19s Dec 18 04:19:57 donnex /kernel: Automatic reboot in 15 seconds - press a key on the console to abort Dec 18 04:19:57 donnex /kernel: Rebooting...

One time they build it, we did all sorts of tests, but once we started to build perl on it it would die. They swapped out everything, and when they got to the power supply, perl would build. The next time they built a system, it stopped in the same exact part of the perl build. It turned out they went to re-use the same power supply. So, I guess all I'm saying is..

Re: My server gets kernel panic every 7th day
Yeah, it has been rock solid. But if the psu was about to break wouldn't the panics be a little more random? As it is right now it get the exact same panic at the exact same time every week.

Re: My server gets kernel panic every 7th day
Hmm okay, sounds like it could be the PSU after all. Thanks. I think I will try to switch it for another one. By the way is there any way to find out what and why find is ran at that time every night to saturday? I would like to find the script/cron/periodic that run it and see if I can make the kernel panic happen again. Then I don't have to wait until next saturday to know if it was the PSU or not. I've searched in /etc/periodic, it's none of my crons that runs find, and found some scripts that runs find but I'm not really familiar with how the periodic scripts works. I need to find the script that runs find every night to saturday at 04:19:57.

Okay, is this hard to do? I've no idea how to look at the dump or how to understand the dump. You don't have to be kernel hacker to understand that?

RE: My server gets kernel panic every 7th day
If I may interject, why should he bother? Seems to me his next step should be setting up a new server with a fresh FreeBSD copy on it, duplicating the 3 jails, then firing off the 4 periodics and seeing if that blows up. If so that is enough info to file a bug report, and he can then simply adjust his script so that the periodics aren't all run at the same time. If someone else wants to spend the time researching this - like YOU for example - then great. >From the Project's point of view, his problems aren't interesting unless they can be reproduced - and from his point of view all he wants to do is fix the problem - and he now knows how to do it. (run the periodic weekly at different times) Grubbing around in a dump traceback does not prove that a problem is reproducible.

You don't have to be kernel hacker to > understand that? It's described in the handbook. Basically: - Build a kernel with debug symbols (you should be doing this anyway). You need the following line in your configuration file: makeoptions DEBUG=-g# Build kernel with gdb(1) debug symbols - Make sure that dumps are enabled. You should have something like this in your /etc/rc.conf: dumpdev=/dev/ad0s2b The device name should be the name of your swap partition, and it must be at least slightly larger than your main memory. - Ensure you have a directory /var/crash, and that the file system in which it resides has enough space for the dump (a little larger than main memory). - When you get a dump, it will be copied to /var/crash automatically on reboot. Go there and get a backtrace. You don't say which version of FreeBSD you're using, but in general this will do it: # cd /var/crash # gdb -k /usr/obj/src/sys/GENERIC/kernel.debug vmcore.0 (gdb) bt The name of the kernel (kernel.debug) depends on how you built your kernel. If it's not called GENERIC, the name of the directory will change accordingly. That's it in a nutshell. There's much more detail in chapter 6 of my debug tutorial, which you can find at http://www.lemis.com/grog/Papers/Debug-tutorial/tutorial.pdf .

This would take a lot of time and money. And if it blows up, it doesn't buy him anything: he still has to find the cause of the problem. If it doesn't blow up, he doesn't know whether it's going to stay that way or maybe reappear in a while when the constellations are right.

Re: My server gets kernel panic every 7th day
Yeah, thank you. I changed the cronjob file so that they run periodic weekly on diffrent days. So I hope I won't get any more panics now. I don't have the time or energy to bebug the kernel atm, maby later but thanks anyway. Anyone else uses jails and noticed the same behaviour? I think I'll do some more testing on a new box when I've got time to see if I can reproduce it there.

Hardware failure is by far the most common cause of "strange panics under abnormal load [such as when the weekly cron job runs]". Kris pgpKAtPBg9AGQ.pgp Description: PGP signature

I've had servers start to flake out in exactly this way when their PS took a dive and was no longer to keep up with peak demands. Kris P.S.

Hmm, I haven't checked the powersuply but I think it is unlikley that it would fail on a find when the box can take very high load and I've done a few rebuilds (kernel + world) on the box without any problems at all.

Unlikely or not, I've seen it happen, and there's no other likely candidate since you said you haven't updated the machine in a year, and it's been stable under the same load until now.
