Ingrid, I am not on the tomcat developer committer list so my reply is just an FYI from my own experience.
I saw unstable performance myself in a very similar deployment of Struts applications similar to yours. I too thought there was a memory leak and there may be, but I don't think it is in the applications themselves. The behavior I saw, led me to think it was related to socket allocation as after a period of time my system began to complain and slow down and other socket related programs began to complain about timeouts, etc. I found that my tomcat needed to use virtual memory to avoid out of memory exceptions. I added physical memory and the problems all but went away, however it still occurs just less frequently. I am using j2sdk1.4.2_09 Tomcat-5.0.28 On Windows XP Pro sp1 Michael Oliver CTO Alarius Systems LLC 6800 E.

We are running an application on Tomcat 4.1.30, and java 1.4.2. Our application is using the struts framework with jsp's, and cocoon to render the xml's. There seems to be a major memory leak at startup - the application seems to constantly be using between 40 - 45 mb of the memory. We also have some memory leak during runtime, when users log on and starts using the application. So far we have not been able to find anything in our code review that will explain these memory leaks, and when we monitor the memory used, there is no obvious reason, nor is there any connection with how the users use our application and the amount of memory being used. We would highly appreciate any help on this topic, and any tips and hints you can provide us with. Ingrid and Tommy -- I am using the free version of SPAMfighter for private users.
