I posted a bug about this, but figured I'd ask the mailing list to see
if someone had seen this.
Bugzilla: http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1746

Basically, I had a dom0, after 57 days of non issues, lock up for 4
hours, completely unresponsive, and then recovered. The domU's were
unaffected except for the fact that I could not shut them down. (
since dom0 was unresponsive ). Although I was able to gain access via
xapi/xencenter, and I atleast had some access ( console, status, etc,
all worked via xapi).

 It seemed to have done a lot of paging and swapping, and there were
faults reported in cpu 3. The load was also extremely high on dom0.

Has anyone seen this?  I could only find one other posting with a
similar issue 

I'm running XCP release 1.0.0-38754c (xcp), any help greatly appreciated.
