Server Crashing

[ukhost4u]

Hello.

We are having trouble with one of our Proxmox systems keeps crashing, after the first crash I updated everything but it happened again. From /var/log/messages I can see:

I can't see any reason for this, can anyone shed any light on this?

Thanks,

you still run Kernel 2.6.24-9-pve, it is very outdated. update to supported kernel branch suitable for your needs.
See http://pve.proxmox.com/wiki/Proxmox_VE_Kernel
