Tomcat quits programm

Hey Guys,

I have following problem:

In a batch-run I produce 1000 Html-sites with my tomcat. When there is a big load on the server following error occurs:

The tomcat-server performs the java-programm in 20-40% of the cases not to the end. But stop processing the programm on varying points of the code and perform the next case.
The server write no message in logs. He only quit the programm.
The tomcat-server produces the jsp-site in 100% of the cases completly. But in errror-case with wrong data, which will be delivered by the java-programm.

Architecture:

Apache-Webserver
mod_jk
tomcat 5.5.26
Struts 1.1-Framework

I am testing with the config-parameter: Xms, Xmx, acceptCount and maxThreads. No Success.

Now i be at a loss.
Can you give me a hint?

Thanks!

When you say "quits the program" do you mean:

1. Tomcat stops executing and exits the JVM.

2. Tomcat stops responding to a particular URL but stays running and responds to other URLs.

3. Tomcat stops responding to all requests but does not exit the JVM.
3a. CPU useage remains tiny
3b. CPU useage maxed out
