Re: [Xen-users] Tools to take a kernel crash dump.



Hi Tej,

The restart (crash) cannot be reproduced but its intermittent. It happens
idiopathic, we cannot predict when it will next restart (crash). We have
been observing this for a month. It ran perfectly last week and it
restarted (crashed) today. Within minutes of restart it again took a
restart. Now it appears to be running fine, the next restart can be in
minutes, days or weeks.

The Dom0 is running on PV Xen 3.1 kernel.

I observed the system logs and there was nothing that hinted a cause for
the system restart.
If I should be looking at any other log, please let me know.
