Description James Norman 2004-12-15 00:15:02 UTC
I have observed a memory leak in the Tomcat manager when starting/stoping a web
application.  With a simple web application (struts-examples) I am allowed ~110
start/stop's through the manager before I get an OutOfMemoryException.  I

My environment:
OS: Fedora Core 2
JDK Build: build 1.4.2_05-b04
Tomcat 5.0.30

application, then run the WebPageConnector, and the OutOfMemoryError will be
