reload no use?
Hi, When I reload an app for the third time, Tomcat hangs, and I have to stop and start it - which is slow as the CPU is being used at close to 100%. This has been the case with Tomcat 5 and 6, Windows 2000, XP and Vista. I have to remember to stop/start Tomcat after the second reload. Is there a better way? Thanks, John

I regularly re-load apps and the only time I have a problem is when the app leaks memory. I would guess your app has a memory leak. Is there anything in the logs?

Nothing that suggests a memory leak. Do you have any suggestions how I might go about finding where this might be happening? It only seems to happen on reload - otherwise, the app runs and runs.

Re: reload no use?
We have a similar problem with our app. We narrowed the problem down to the way we have constructed/used our connection pooling. Our solution for the short term is to restart the server each time we update the app. At some point, we will get time to restructure the connection pooling process so that we are not holding onto objects that can't be freed.

It only seems to happen on reload - otherwise, the app runs and runs. Get a profiler - I use YourKit since they have free license for open source development - and test your application with it. There are lots of things that can catch you out on re-load and not at other times as the application gets a new classloader.
