I am running a middleware application in the tomcat environment described,
below. After rebooting the server, the memory consumption is couple of
gigs. Couple of weeks later, I get a message, I am out of memory.
Moreover, I need to bounce the whole server to start fresh.
Here, the log. I am quite sure how to go about troubleshooting it. Any
help is greatly appreciated.
The application has a memory leak. You need to get it fixed.
catalina.out.prob:SEVERE: The web application [] appears to have started a

failed to stop it. This is very likely to create a memory leak.
