I'll admit, I have very little experience working with a profiler - but I think I need one. Someone e-mailed me about testing all of AppFuse on a super-beafy box, and he got OOM errors after 17 minutes. For a dual CPU, 2Ghz Opterons, with 2GB RAM running RHEL3 workstation, it only made it to the Spring/AppGen test, which is #8 of 21. On my PowerBook, it makes it to #12, but my Linux box only make it to #8 too. My guess is there's some sort of memory leak in one of the testing tools - Tomcat, Cargo, WebTest or AppFuse itself.
Anyone have experience attaching a profiler to their Ant build or testing process to look for memory leaks?
