dom0 rebooting without any reason
I have some kind of problem with my xen server.
Here is some basic info:
Linux version 2.6.26-2-xen-686 (Debian 2.6.26-17lenny2) (email@example.com)
two domus: with 2048 and 256 of memory.
Now, every two hours or so dom0 reboots without any reason, no log messages, nothing. If i stop xend (xend stop) then server works without any reboots perfectly. Please help me to identify problem, i know it is difficult because i have no information what can cause it. Hardware was tested throughtly for two weeks - everything is perfect.
It works without any gliches with xend started too except rebooting 'thing'.
Is there any way to 'catch dump' when that happens? (unfortunately kernel has no errors too)
