My server went down suddenly and the ISP supports says it may have had a segmentation fault. I am wondering how to track down and possibly fix this so it will not occur again?

It "may have had" ? So they don't actually know? – gparent Dec 17 '12 at 15:50
@gparent actually no. That's the only explanation that I've got. – alfish Dec 17 '12 at 15:52
Is that a shared or dedicated host, vserver or physical/vm? – rackandboneman Dec 17 '12 at 16:27
It's a dedicated server – alfish Dec 17 '12 at 16:30
Not enough information has been provided here for us to help you. There are so many different reasons for a segmentation fault, and to fix it you'd have to be ready to edit the source code after analyzing the core dump and make the change and make a new binary. – mdpc Dec 17 '12 at 17:45

Such segfaults are usually logged in the system's syslog facility. The exact name of which changes by distro, though dmesg should have it if it's recent enough; it'll be in /var/log one way or the other, though.

Interpreting the message will be another story entirely. But at least you'll know what faulted.
