Server crashing after:

Server strangely crashes! No ping and no access at all.
The last message on Kernel is:
May 8 21:52:02 h09 kernel:[5343]: segfault at 7f9a0c8ea490 ip 00007f9a0c8ea490 sp 00007fff34d988b8 error 14

Is there anyway of debugging!?

What is the output of “free -m” on your system? It’s possible that available RAM/swap could be related to the issue you’re seeing.
