Understanding kernel events /var/log/messages

Latest response

hope someone out there can help with this.
Our linix redhat 5.6 server crashed and the last entry in /var/log/message is
:
Jan 7 09:29:08 earpsteporawl01 kernel: gm[29664]: segfault at 000000000000001b rip 000000000824eb89 rsp 00000000ff850e50 error 4
Jan 7 09:29:09 earpsteporawl01 kernel: gm[29667]: segfault at 000000000000001b rip 000000000824eb89 rsp 00000000ffdbc6d0 error 4
Jan 7 09:34:00 earpsteporawl01 syslogd 1.4.1: restart.

There are hundreds of these kernel: gm segfaults and I cannot identify what this is.

As you can see, the server restarted at 0934.

Hi Garry. Hopefully someone from the community will be able to assist with this, but it might be difficult to investigate without a support case.

Th "kernel: [number]: error" notation usually indicates that one of the kernel's device-drivers is crapping out. In this case it would be your gm driver that's crapping out. You might do an lsmod | grep gm to see if gm is currently linked into your kernel. From there, you could possibly do a modinfo -F description gm to get an idea of what the gm module does (cursory Google search makes it look like might be an Intel graphics module). That will at least get you into the area of your problem.

Also, with the snippet above, not really seeing that your system has crashed, just that syslogd has restarted?

Garry,

https://bugzilla.redhat.com/show_bug.cgi?id=237803 is the thing that pops-up in Google. This bugzilla is about a graphics programm on Fedora gallery2.

Does this apply to your issue?

In general: What program is running just before the crash?

Kind regards,

Jan Gerrit Kootstra

Tom, there is no such module listed for gm, which as Jan has also found is related to GraphicsMagick. Thanks for the
Jan, thanks for the url, this is indeed the same problem. GM is used for images an thumbnails. Odly though, GraphicsMagick is not installed but ImageMagick is.
We have a third part that supports this image processing so i will speak to them.
Many thanks for you help.
