Maybe you got some memory leak in your code. Use a memory-inspecting
tool and check for static objects.
If you check your memory usage, maybe you'll find that you eat all the
memory available, so you should tune your tomcat server changing the
memory parameters.

Hello for everybody;
We have a big trouble with our Web Application. Our Tomcat 5.5 Server is
working properly, as we can see. The problem is concerning to the Web Project.
It’s frizzing randomly. It doesn’t matter how many time was reloaded. From this
moment never user can get in the Web Site. At the browser address bar we can
see the session id that was assigned to the new session, but never the home
page is presented, and we must be going to reload it. This reloading is making
on the Tomcat Server.
Web application historical summary:
The Trapsatur Project was hosting on a Tomcat 4 Web Server, it was installed in
our offices. It was working almost properly, but slowly. Cause that, we decided
to get out this Server to be housing at office’s ISP, front to Internet. At
this moment we passed to Tomcat 5.5.26. It was begin of troubles.
We are adjusting the Web Application and the Tomcat Server continuously. We
resolved problems with DB connection, someone errors with SMTP server. In
addition we adjusted several Tomcat’s and JVM’s parameters. Now we are doing
some tests. We have assumed that the problem is the difference between
servlet.jar used by our Web Project, and the servlet.jar used by Tomcat Server.
We want to thank in advance any help from any body.
Best regard;
