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

Hi, All
I'm running multiple Tomcat4.1.18/JSDK1.4.2 instances on Windows 2000 (SP3)
as services. Unfortunately, those tomcat services randomly stopped
unexpectedly. Windows event log didn't tell much detail, Tomcat log either.
Does anyone have this kind of experience? How can I address it? Any
information appreciated.
