I have a process running on a router (CentOS 6.3 stripped down) that telnets out to another server and reports stats every minute. The router has crashed a few times over the last month or 2, and the vmcore always says something like this:<br />
<br />
<br />
KERNEL: /usr/lib/debug/lib/modules/2.6.32-279.19.1.el6.x86_64/vmlinux<br />

PANIC: "Oops: 0000 [<a href="http://bugs.centos.org/view.php?id=1">0000001</a>] SMP " (check log for details)<br />

STATE: TASK_RUNNING (PANIC)<br />
<br />
Specifically it's always the command "telnet" that seems to do it. I can't tell if it's actually telnet doing it, or if telnet is tripping over something else.<br />
<br />
I've cleaned the vmcores up, but if it happens again, I'll attach one to this report assuming it falls within your file size.
