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

[Sreeharsha Totakura <sreeharsha.totakura@xxxxxxx>]

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.
