Odd Memory Problem

I have been battling a memory problem for a few months now with no luck. I have used profilers and everything else you could imagine. The problem is we have never been able to duplicate it on the testing servers it only happens on production which does not see much load at all (100 users a day).

Connection is Closed

I keep receiving a Connection is Closed error in my tomcat localhost_log. After receiving this error I have to restart tomcat to reconnect to oracle. Is there any type of auto reconnect parameter? Thanks,

Garbage collector

I was wondering if anyone had a preference in which garbage collector to use. I am currently using -XX:+UseConcMarkSweepGC but I was wondering which would be considered the best or most commonly used. Thanks
