Subject Re: Tomcat crash @ midnight - but why?
Date Wed, 26 Sep 2007 14:24:42 GMT
Check Windows Scheduled Tasks, to see what runs around that time. Could 
be a resource issue. A background task or even a load spike
from a search bot. How much memory is allocated to the VMWare instance? 
Also did you check the Tomcat logs?
