Hi all,

Im currently working on my bachelor thesis in data and network administration and my ubuntu server (13.10) crashed (froze) during the fio tests I was running.

This happened after about an hour of running the test, the syslog gave me these messages:

Code:

Mar  4 12:55:06 puddy kernel: [12809.900750]  [<c162df8b>] error_code+0x67/0x6c
Mar  4 12:55:06 puddy kernel: [12843.677837]  [<c162df8b>] error_code+0x67/0x6c
Mar  4 12:55:06 puddy kernel: [12843.780600]  [<c162df8b>] error_code+0x67/0x6c
Mar  4 12:55:07 puddy kernel: [12870.793433]  [<c162df8b>] error_code+0x67/0x6c
Mar  4 12:55:07 puddy kernel: [12870.901120]  [<c162df8b>] error_code+0x67/0x6c

and I cant seem to figure out what caused these error messages, are there any other places I should be looking for error messages ? Or do anyone here have som experience with these ?

The server is a frontend server for a backend storage server, connected through iSCSI. Both the frontend and backend servers are running ubuntu server 13.10.

The server is a HP DL360 G6, 8CPU, 12GB RAM.
And we have a replicated server (same config) that does not crash during these tests.

I'm at my wits end, could someone help please ?

Thanks in advance,
zingoto

There should be messages leading up to and after the one you posted and without those there's really nothing to say. For debugging see https://wiki.ubuntu.com/Kernel/Debugging and more specifically https://wiki.ubuntu.com/DebuggingKernelOops .
