You ought to look into the cause of this problem by running a combination of ps, top, etc commands and getting a thread dump by killing the threads. Generally it turns out that some application/servlet is the cause of runaway threads. It would be a good idea to look into the bug database/forums on the sun java site for JSDK1.4/Linux issues. I know JSDK1.3.x/Linux had a couple of issues with regards to sockets.

Please respond to

Can you try with IBM JVM, as it works well on linux in cae of performance
as well as memory usage

Subject: RE: HELP, PLEASE! Tomcat creates too many threads!
I am curious about the same thing. My app isn't fully up and operational
yet so I do not know for sure if I suffer from the same problem, but I have
noticed that while doing some testing new threads are getting started, and
it usually takes a restart to get rid of them.
I've seen this question posted a few times, but haven't noticed any
'resolution' or possible solutions. Can anyone recommend things to check
for, settings to make, or perhaps any documentation on the issue?
Is it possible that this could be a JSDK 1.4 issue? It's the only common
link I've noticed between my set up and other posters with this problem.
Thanks :)

Subject: HELP, PLEASE! Tomcat creates too many threads!
Hello all,
Im running Apache and Tomcat in a Linux machine, after a couple days
and several accesses to my applications, Tomcat creates several
threads/processes that stay sleeping, as you can see at the end of this
e-mail.
Im using Tomcat 4.0.4, Apache 1.3.26 with mod_webapp, and Java
1.4.0_01.
If I don't restart my tomcat, it will exceed the maximum number of
processes the user can execute and it will block, turning my applications
offline.
Is there any solution to this problem? How is it possible to avoid the
creation of so many processes?
I really appreciate any help you can give me.
These lines are only a few ones I get when I run the ps -elf command:
