Hey Jan,

Dom0 is Debian Etch amd64 (haven't upgraded this Dom0 yet) running 
2.6.26-bpo.1-xen-amd64.  Xen version is xen-3.2-1-amd64.  Plenty of leftover 
memory and swap.

DomU is Centos 5.3 Final amd64, running the dom0's kernel 
(2.6.26-bpo.1-xen-amd64).  DomU has lots of memory and plenty of swap (added 
because I suspected it may have been a problem).

One possibility I am beginning to suspect is that domU may be filling up /tmp 
(using /usr/tmpDSK for some reason).  Not sure on that, though.  I may try 
removing that from the fstab and see if stability improves...

Nathan
