Subject Re: Javac memory leak
Date Thu, 21 Nov 2002 16:35:37 GMT

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 a memory leak though. if you use a lot of static
variables, that could easily account for objects getting promoted to old
memory
