Given http://tomcat.apache.org/security-6.html, downgrading is really bad
advice. Added to which, it won't change anything.

It is, and my previous on this thread explains it.

Trying different Tomcat versions isn't going to help.

No need, we already know. As would you if you had a) used Google, b) looked
in Bugzilla or c) searched the archives for this list.

I think you mean free memory here. Increasing memory usage during a load
test isn't necessarily an issue as long as it levels off eventually. If you
suspect a memory leak the only real way to be sure is to use a profiler and
look at the actual usage.

No need to experiment. A little research was all that was required.
