Hi folks,

I have several servers running the Xen packages from Debian Lenny - the cpu architectures are ranging from dual pentium III, dual xeons from 4 years ago and current quad core xeons. All share a problem: they frequently crash.

The physical machine then reboots, and in the logs there is absolutely nothing. The intervals between crashes range from just a day to around 30 days in the max, but mostly it happens roughly every few days. The only pattern I found so far is: the more virtual machines on the host, the infrequent the crashes (that alone is weird).
Wow... I just (a week or so back) migrated a server from Debian Lenny on bare iron to Lenny on Xen. I'm seeing a similar problem - about once a day the physical machine crashes and reboots, with nothing in the log to give any indication why.

I'm in the process of identifying and installing tools for capturing pre-crash activity - any suggestions would be welcome.
