[Xen-users] Why does my DomU keep going mad?

[Lyle <webmaster@xxxxxxxxxxxxxx>]

Hi All,
  I've got a DomU that sometimes goes mad. I can't ssh or usually even 
console to it. The time I did manage to console I got a load of dumps 
about being out of memory and swap, but couldn't run any commands to 
find out which process had gone mad :(
  From Dom0 I can see the DomU at 100% CPU and can only stop it with a 
destroy. What can I do/check to find out why this happens? Sometimes 
it'll be fine for weeks on end, others it'll go wrong almost every day. 
The servers average load is very low, around 0.1. I assume there is a 
process that goes wild for whatever reason, but no idea where to start 
to track it down :(
  I'm running the latest CentOS, any help much appreciated.


Lyle
