Tomcat takes 100% of CPU

[Dave Finch]

I have an NT 4 server running IIS and Tomcat 3.2.1 using the ISAPI filter and the NT Service. After about 10 minutes of running and not a single request the tomcat (java.exe) process takes 100% of the CPU usage. I initially thought it was a problem with the code but it happens whether any requests are received by the web server or not and I have the same configuration and code running on another server. I am also sure it is not a hardware issue.   Any ideas would be appreciated.   TIA, Dave Finch
