FC2 locking up randomly

[Tim Ballantine]

This has only just started happening. I have had the server (which is 
currently being co-lo'ed) running for 6-7 months and it now randomly 
freezes completely. Last week I updated to the 2.6.9-1.3 fc2 kernel and 
about 4 days after that it started freezing. I thought there must be a 
connection, so I then upgraded to 2.6.9-1.6 kernel, still happening. I set 
grub to boot from one of the older kernels I had been running for months on 
and it's still doing it.

Twice today now. All fans were working and temperatures were the same as 
before. Had top open, memory usage stayed roughly the same, no new 
processes, cpu stayed at about 35%

I'm waiting for redbus to reboot it then I can run memtest but I think that 
will come back ok.

Any thoughts?

Cheers,
Tim
