Subject Re: Tomcat shutdown does not kill java process
Date Fri, 30 Aug 2002 14:35:03 GMT
Make sure you do not have any servlets or beans creating non-daemon 
threads. A java process will run while there exists at least 1 
non-daemon thread.

Perform a thread dump on your java process and see if this is the case. 
See previous threads (or google) on how to perform a thread dump.
