Raja, We had the same problem, running Tomcat on Solaris. I think it is a JVM bug, not a Tomcat problem - so this is technically off topic, please excuse me. We changed to a later build (92, I think) of the Sun HotSpot 1.3.1 JVM and that fixed the problem. Now we are on 1.4.1 and everything still works fine.
The problem for us was a JIT compilation error, due to a bug in the JVM. If you want to see what is being compiled, put the -XX:+PrintCompilation in your java command (inside catalina.sh). This will send the names of classes being compiled to stdout (catalina.out?) and you can see which class was being compiled just before it crashed. If it is one of your classes, make some arbitrary changes or try a different algorithm, to see if that fixes it. Really, for a JVM bug, the best thing is to upgrade to a later version of the JVM. It might slow down your production machine a bit - we only used this option on half the machines in our server farm. If your problem is not a compilation bug, or you are not using HotSpot, I guess you will have to dig further. Chris PS - If anyone can tell me why an unchanged webapp uses twice as much CPU in Tomcat 4.1.18 as it did in 3.3.1, I would be most grateful.
