Hi,
we have a couple of nodes based on CentOS 6 and Xen4CentOS. Unfortunately
some of these nodes keep crashing frequenly.
We use the latest versions:
# uname -r

Our configuration looks as follows:

(vif-script vif-bridge)
(dom0-min-mem 1024)
(enable-dom0-ballooning no)
(total_available_memory 0)
(dom0-cpus 0)
(vncpasswd '')
I've attached the logfile information regarding the latest crash as
crash.log?
Does anybody has an idea how to solve these issues?
Kind Regards
Daniel Bradler
