I'm not sure that this is it, but you might try setting the JVM min and max memory limits when starting Tomcat by adding the following to $CATALINA_HOME\bin\catalina.bat:
set JAVA_OPS = -Xms100m -Xmx100m Default for the JVM I believe should be 64mb, but who knows. Why are you using jdk 1.3.1? Do you have existing code that is not compatible with jdk 1.4? We are running Tomcat 4.1.24 as a service under Windows 2000 Server accessing an SQL Server database on the same machine with JDK 1.4.1_01 and it is working.

We are running Tomcat 4.1.24 Binary release, as a Service on Windows 2000 SP3 and SP4 Pro version. No JSP just servlets. The Tomcat instance is hosting 2 servlets that talk to a local SQL Server 2000 database on the same machine. A VB 6 client is talking to the servlets via http post etc, and exchanging XML documents for requests and replies. Running as a Service, with JDK 1.3.1 as the JVM the service will crash after about 10 minutes of activity. Just prior to the crash, available memory will decrease to 0 and the system will slow to a crawl with a lot of disk activity, paging I imagine. Running Tomcat in a window alleviates the problem entirely, so I am assuming there are some parameters that are being passed via the Startup.bat file that are not happening with the service. Or perhaps to the JVM, I am very new to Tomcat so I am not sure how to accomplish this. However we really want to have Tomcat running as a service since this is a laptop app being deployed to hundreds of our users, and we don't want them mucking about with the Window created by running Tomcat as a windowed service. Plus, having it run as a service means it is one less thing to worry about in our application code. However we can't deploy the app if it crashes every 10 minutes. Any help or suggestions would be appreciated.
