Shapira, thanks a lot. I resolved the problem with the coyote connector and tomcat 4.0.4 . I still don't know what was happening, but I got a good performace now, and just a few java threads on my ps command result. I read the paper you send and used your class, nice paper by the way. Again, thanks for your attention, and anything you need that I can help, I'll be around.

You can search the list archives, a few months ago I posted a simple "list all threads in the system" class that you can use to see exactly what's going on. Please be careful to distinguish between threads in the JVM and OS-level threads. The mapping is not always one to one. A good document can be found here explaining the different JVM threading models: http://java.sun.com/docs/hotspot/threads/threads.html Yoav Shapira Millennium ChemInformatics >-----Original Message----- >From: Ronaldo [mailto:[EMAIL PROTECTED]] >Sent: Tuesday, August 20, 2002 8:31 AM >To: Tomcat Users List >Subject: RES: Too many threads > >Thanks for your atention Shapira, but I did search a lot in google for this >topics, but nobody seemed to have this kind of problem.
