Hi Yoav, oops. I didn't line out that this kind of memory tracking is for testing locally with my dev environment to see how tomcat does when handling 100.000 records of a ResultSet or so... and when memory does show up again.
Thanks for the link, I'll investigate it later... Is the JVMPI powerful enough to get used in a memory tracker for tomcat (I haven't used it yet)? Wouldn't it make sense to have a monitoring app for memory and database connections for Tomcat (i.e. dbcp/poolman functionality + jvmpi in one admin app)? thx Johannes
