I would argue that sites that don't have a lot of load should simply turn off tag

significantly from tag pooling.

like a lot of objects are promoted to old memory from heap. It doesn't
necessarily constitute a
/ directory, the memory
allocated to java is 40megs.
I even ran it with OptimizeIt and I don't see any memory leaks.

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 mean
you never know. if it's a slow leak, precompiled pages may not exhibit
the leak. I only discovered the leak in our custom tag when I put the
app under moderate/medium load. Under light load the bug wasn't
apparent.
I'm guessing if you hit each page individuall slowly, the bug doesn't
appear. If

I'm on win2K also.

Hmm, that sounds bizzare. I'm been using/testing 4.1.10-4.1.12 on both
solaris and windows with jdk1.4.1. I've ran several stress test using
JMeter simulating light to medium (64 concurrent connections) load for
1-10K requests without any problems. My pages are heavy on JSTL, so they
are fairly
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?

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.
