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.
