I've been load testing Tomcat 4.0b3, Tomcat 3.2.1, and Tomcat 3.2.1 + Apache. I got
T3.2.1 (both configurations) to hang within a couple of minutes. The only solution
was to kill the threads that have open connections; not nice. I'm focusing on
Tomcat 4.0b3 as I have yet to break it, but then again I haven't hit the outer
limits of what the host box can do (mem, cpu).
I have yet to try Tomcat 3.2.2 beta 3 or 3.3 milestone 2.
