This morning I had a hard lockup on my co-located server. I had it rebooted
and after checking the logs I discovered alot of these messages in my logs:
Sep 10 10:19:09 infamy kernel: kmem_alloc: Bad slab magic (corrupt)
(name=sock)
Sep 10 10:19:51 infamy last message repeated 14 times
Sep 10 10:21:12 infamy last message repeated 12 times
Sep 10 10:22:13 infamy last message repeated 10 times
Sep 10 10:23:34 infamy last message repeated 17 times
Sep 10 10:25:00 infamy last message repeated 21 times
Sep 10 10:26:02 infamy last message repeated 214 times
Sep 10 10:26:09 infamy last message repeated 23 times
Finally, from what I can tell, the server died with this:
Sep 10 10:29:12 infamy sendmail[497]: NOQUEUE: SYSERR(root): getrequests:

Sep 10 10:29:12 infamy sendmail[497]: problem creating SMTP socket
After a reboot everything seemed to be working ok. Then a few hours later I
was unable to connect to check my e-mail via POP3. I had been able to
connect via POP3 after the reboot. I watched the logs and every time I
connected I discovered this in /var/log/messages:
Sep 10 23:24:30 infamy inetd[440]: pid 3298: exit signal 11
It seems that ipop2d, imapd, and ipop3d all segfault all produce:
Segmentation fault (core dumped)
Any ideas what's gone wrong?
Thanks for any help,
