True, there is a definite memory leak when using a connector and a front-end webserver (e.g. mod_jk, mod_jk2)
You can try fixing this by putting:
# Fix memory leak bug in tomcat 5.0.19: request.registerRequests=false
in $TOMCAT_HOME/conf/jk2.properties

We had memory loss with 5.0.19. We profiled a 5.0.19 web app and found that memory was not being garbage collected too well. As soon as we upgraded this went away and was proven by th profiling. Start by trying out 5.0.27 and see how it goes. If it still happens then take Yoav's advice and profile you app using the (now freeware and excellent) JProbe (www.quest.com) and go from there.

Hi,
We upgraded our Tomcat server from 3.0 to 5.1.19 about two months ago (linux
machine). Since then it frequently crashed (twice a week). It seems like the
crash was caused a web crawler. This web crawler generate many threads and
quickly drained server memory. The log file showed
java.lang.OutOfMemoryError. When we use Tomcat 3, this crawler didn't cause
this problem.
Does anyone have any suggestion on how to solve this problem (we don't want
to block this crawler)?
Thanks.
Matt
