any jsp page, the

Not compiled
Memory starts at 39635 and ends at 58760
Does this not look like a memory leak in the jsp compile code??
Thanks,

I also have no memory leak problems now with Tomcat 4.1.12.
But i'm using jikes instead of javac as jsp page compiler.
Whats about switching to jikes. If the memory leak problem is
gone with jikes, javac still leaks memory, otherwise
??
Thanks,

Just to double check against tomcat 4.1.12, the memory usage
seems normal to me John
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
optimizeit and see what it shows.. Thanks for all your time..

I haven't seen the memory leak on solaris or windows, but isn't the leak
only on linux?
I thought jasper2 fixes the problem with com.sun.tools.javac.Main since
it uses the system native javac?

you never know. if it's a slow leak, precompiled pages may not exhibit
