CentOS - Dec 2008 - Fedora 9 domU on CentOS 5.2 dom0 - very unstable?

I am running a Fedora 9 domU on CentOS 5.2 dom0, and it is quite 
unreliable. Every few days I have the following phenomenon:

- many applications do not work at all (e. g. Nagios 3.05 stops checking, 
but the cgis work perfectly, the web server works as well)
- system processes run into time outs (e. g. logging in via ssh runs into 
timeouts <<"connection reset by peer">> after many
seconds, logging into
the console does not get finished ever, no error, no refusal) and similiar

All I can do then is destroy the domain (xm shutdown does not lead to 
anything either).

Is this a known phenomenon? Is there any way to work around it? I do not 
have these problems with CentOS 5.2 domUs on the same machine (at least not 
that massive).

Every hint or help is appreciated.

So do i.

But for me, everything works like a charm. 

[root at xen ~]# uname -a
Linux xen.unixkiste.org 2.6.18-92.1.13.el5xen

Fedora release 9 (Sulphur)
Kernel 2.6.25.3-2.fc9.i686.xen on an i686 (/dev/hvc0)

Yes, i should reboot to a newer kernel. :)
