Hi,
On my test environment I am just on 64 Mb of memory. I know I can
increase that - but that still will not fix my initial problem.
My application is using 40 - 45 Mb - and that is more than I thought it
should use.
At the moment I have no JAVA_OPTS.
Thanks for trying to help. :-)
Ingrid and Tommy

Hi,
Can you share how much memory do you have and how much used by tomcat
and what JAVA_OPTs do you have.
Thanks a lot,
Mark.

Ingrid,
I am not on the tomcat developer committer list so my reply is just an
FYI from my own experience.
I saw unstable performance myself in a very similar deployment of
Struts applications similar to yours. I too thought there was a
memory leak and
there may be, but I don't think it is in the applications
themselves. The
behavior I saw, led me to think it was related to socket allocation
as after
a period of time my system began to complain and slow down and
other socket
related programs began to complain about timeouts, etc.
I found that my tomcat needed to use virtual memory to avoid out of
memory exceptions. I added physical memory and the problems all but
went away,
however it still occurs just less frequently.
I am using
j2sdk1.4.2_09
Tomcat-5.0.28
On Windows XP Pro sp1

Hello.
We are running an application on Tomcat 4.1.30, and java 1.4.2.
Our application is using the struts framework with jsp's, and cocoon
to render the xml's.
There seems to be a major memory leak at startup - the application
seems to constantly be using between 40 - 45 mb of the memory. We also
have some
memory leak during runtime, when users log on and starts using the
application.
So far we have not been able to find anything in our code review that
will explain these memory leaks, and when we monitor the memory used,
there is no
obvious reason, nor is there any connection with how the users use
our
application and the amount of memory being used.
We would highly appreciate any help on this topic, and any tips and
hints you can provide us with.
Ingrid and Tommy
