Steps to reproduce: Server crashes randomly about once per day.
Comment 1 Alan 2010-01-27 12:24:01 UTC
These look like fairly random memory corruptions. Is the hardware ECC memory and has the memory been tested.

Also I see reiserfs is loaded - is it heavily used by this system (just comparing it to another similar looking report)
Comment 2 Krzysztof Mościcki 2010-01-27 14:32:34 UTC
There was nothing meaningful in ipmi and mcdelog logs but RAM wasn't chcecked yet.

if it could be the problem with reiserfs maybe changing it into ext3 could fix it?
Comment 3 Krzysztof Mościcki 2010-01-27 14:42:13 UTC
RAM is with ECC.
Comment 4 Alan 2010-01-27 15:00:17 UTC
It would be a useful test to run without riserfs for a bit if that is practicable. It would help cut down the possibilities.

Have you had older kernels on this box that were stable ?
Comment 5 Krzysztof Mościcki 2010-01-29 08:47:05 UTC
This is a new box, not tested on older kernels.

All partitions with reiserfs been converted to ext3, and today was a new kernel panic:

[75869.296074] Kernel panic - not syncing: Fatal exception in interrupt
Comment 6 Marek Kierdelewicz 2010-01-29 09:48:43 UTC
Hi, Krzysiek's co-worker here. Box is running two bonded igb interfaces in IntrMode=2 (MSI-X + RSS). Could multiqueue be somehow involved?
Comment 7 Krzysztof Mościcki 2010-02-01 15:14:20 UTC
At this time, igb module is loaded with the following parameters: "intmode=1, no rss, no msi-x", but tonight was a server crash.
In dmesg I found:

Comment 11 Marek Kierdelewicz 2010-02-04 06:13:47 UTC
i/o scheduler was switched from deadline to cfq, kernel didn't panic for nearly 48h, tests continue
Comment 12 Marek Kierdelewicz 2010-02-04 07:36:37 UTC
another panic, distinct thing is:
- box never panics under heavy load
- panics occur at load minimums (night time) and shortly after taking load of the box
Comment 13 Marek Kierdelewicz 2010-02-09 08:19:51 UTC
Krzysiek was able to reproduce panics by deleting iptables rules with "-m socket" match (part of tproxy suit)

After restructuring of iptables ruleset we were able to overcome socket match problem (by excluding some traffic). It seems that slab corruptions were caused by traffic destined to local port 80 hitting "-m socket" rule or TPROXY target. 

If no traffic destined to local port 80 hits "-m socket" rule or TPROXY target there's no problem with kernel panic after iptables rule deletion.
