that is unusual. I've done baseline performance tests with the standard examples and haven't seen that kind of behavior with 4.1.10-12. Can you start tomcat with verbose:gc and see what kind of output you're getting. Just because the memory allocated to Java is 58megs at the end, it doesn't

This is from the examples jsp right? or are they from your webapp? the latest optimizeit has a leak finder feature. you may want to download the trail version and give it a shot. from the data it looks like a lot of objects are promoted to old memory from heap. It doesn't necessarily constitute

Oracle comes with it's own JDK and sets some environment variables. if you want both to coexist, hardcode the JDK in your catalina script. when you uninstall, it reverts the environment settings and fixes your tomcat problem. usually, that's the cause. peter [EMAIL PROTECTED] wrote: Hi
