Re: which memory profiling tool is better for tomcat?
Try the Reference Scanner from http://jb2works.com/ - if you want to find memory leaks. It runs from a browser windwow, also remote. Tomcat-Howto (Singel app and full tomcat) is there too. I had used OptimizeIt but was not happy with it, before i decided to write the Reference Scanner. Read this FAQ http://jb2works.com/memoryleak/index.html for more information.

The options I've come across are Rational Purify and JProbe. Rational Purify doesn't seem to be as tailored for Web Servers as JProbe, and I've found nothing in Rational Purify's documentation describing how to run a Web Server in non-graphical Linux bur monitor from a Windows machine which I do see that JProbe do.

Re: java.lang.OutOfMemoryError
Hi Marco Give 'The Reference Scanner' a try and make heap snapshots and check the diff between snapshots. I just published the tomcat-howto. You find the Software here http://jb2works.com/ If you need more help, you reach me via mail.
