How can we stop a KVM from freezing

[webservio]

First of all we love Proxmox for many reasons and intend to continue using it. However we have experienced this with almost all versions of Proxmoxe including the latest 2.1. Certain of KVMs running linux Debian Lenny
freeze in randomly and the only way to deal with it is to stop and restart the KVM. We tried increasing CPU units to maximum as well as increasing allocated Ram but still same experience. What exactly can we do to prevent this?

Many thanks,

Which kernel do you run on your KVM Lenny guest? Install 2.6.32 inside.

Here is the info from uname -a
2.6.33 #1 SMP

This is the only OS that we have experienced problems with.

2.6.33 in Lenny, are you sure?
