I assume no other Java programs are running and that all 36 of the entries 
you're seeing in the "ps" output are from Catalina. This implies that 36 
threads have been created by Catalina. Under Linux, each thread shows up 
separately in the ps listing.

On my Windows system (Win 2K, Tomcat 4.0.4, J2 SDK 1.4.0_01) merely 
starting Tomcat causes 30 threads to be created, corresponding to the six 
configured connectors each with a "minProcessors=" attribute of 5. Check 
your ".../conf/server.xml" file for <Connector> elements and add up all the 
minProcessors= attributes. That should be your 36.

If the number grows and stays up even when there are no requests being 
processed, it might be a sign of a problem. If the number fluctuates but 
returns to 36 when Tomcat is again idle, then things are OK.
