JVM and use of memory
When I start tomcat, it process use 44M and 16M res. (aprox).
But when I work, and work, and work.... it process use
49,52,60,....80,100,120 M and crash tomcat !!!
I have JSP pages that use 8 beans... then memory used it increases more
quicky....
I'm using:
Tomcat 3.3
JDK 1.3.1
Apache 1.3.20
Solaris 2.8
Help me....!!
Thanks.
Roy

Well, if you upgraded to 3.3 to solve the problem, that tells you
something... It's not the container, but the application... 3.2.2 has a
release tag, 3.3 is a beta (B1 or B2)... A memory leakage wouldn't have gone
out in a release tag...

Thanks...
Last week I upgrade tomcat from 3.2.2 to 3.3 for to solve the same problem.
I think that I can release memory (used by servlet or beans) from JVM....
I will read JSP specification.

AFAIK 3.3 doesn't have any bug related to memory (AFAIK, but I'm not
developing that engine). You might want to try and downgrade down to 3.2.3
(which is the last non-beta release), or 4.0b7 which I use on several
production environments and I've never seen failing for out of memory
exceptions...
98% is something you don't release in your web application/jsps

Roy,
Do you have any output in the logs either from Tomcat or the JVM?
