Can you be more specific about the problem? Any UBC failcnts?

Apache 404 error is unlikely to be an openvz related problem, have you checked apache's log files?

Overall, it sounds like application level problems and you should start troubleshooting the system by analyzing the syslog files as you duplicate the problems.

UBC Failures?

always the first thing to check whenever there is a problem.
