This sounds like your sessions arent getting invalidated. If you look at the tomcat manager app it will tell you how many there are and you are likely to see this number increasing. The reason that it starts bloated is because when you shutdown the sessions get serialised and then reloaded once you restart tomcat.
To stop it starting up bloated remove the SESSIONS.ser file from your context's work directory, while the server is shut down. As a more permanent solution you should explicitly invalidate the sessions in your code or reduce the session inactive timeout but i'd suggest the former.

I have been running JProbe on my web application for some time now and have not noticed any memory issues, as in, memory not being released by the application. This is what my environment look like: - The environment is a cluster running on 2 Sun Blade servers running RedHat 9. Clustering is handled by my app and am not using tomcats clustering. - Apache 2, httpd 2.0.49 - Tomcat 5.0.25 - Java 2 SDK version 1.4.2_04 - Ant 1.6.1 I modified the server.xml to show the following change advised by one of the posts on the list. <Engine className="org.apache.catalina.core.StandardEngine" debug="0" defaultHost="localhost" mapperClass="org.apache.catalina.core.StandardEngineMapper" name="Standalone" backgroundProcessorDelay="-1"> I also set the JAVA_OPTS to JAVA_OPTS="-Xmn32M -Xmx128M -XX:MaxHeapFreeRatio=30 -XX:+UseParallelGC". I can change the -Xmx to 256 or 512 but that is not a solution, its just a way of temporarily getting away from the problem. I have the following symptons - I got OutOfMemory Exception today after moving to tomcat 5 a couple of months ago, but have been noticing some funny memory usage. I was previously using tomcat 4.1.30 and was getting memory exceptions almost everyday. - When I shutdown the server and restart it java starts bloated, same size as when it was shutdown. I have tried this with the application removed but no difference. Attempts: - I have tested the app on windows machine and VMware installations of the same environment(RedHat 9) and can't duplicate the problems. - I have used JProbe to monitor memory cleaning in both environments and have found nothing. - I am in the process of getting JProbe installed on the cluster and will be able to monitor thereafter. I can use some really good suggestions at this point.
