Subject Re: Tomcat service on Windows 2000 stopped unexpectedly

Your Java Virtual Machine(s) could be crashing.
Search for "HotSpot Virtual Machine Error" in catalina.out and your 
application logs.

We had a problem with crashing JVM's (JDK 1.4.1) on Tomcat 4.1.24 (on 
Linux) and using ConcurrentGC/ParNewGC.
With ParallelGC the JVM works stable (although Garbage Collection 
performance is worse and leads to OutOfMemory from time to time,
since the application needs a lot of temporary memory for PDF generations 
with FOP)

Try using different Java Options and Collectors or JDK 1.4.1
