Were you using Java 5?

Well it seems that I was able to get rid of the nasty memory leaks.
The problem is, that they weren't real memory leaks after all. I
noticed that if I pressed the "GC" button in the JConsole tool, that
all unnecessary Memory was freed. As far as could find out, this is a
problem with the default garbage collection method used to free
memory. This uses a fast but inaccurate way to free unused memory
blocks. I could have started testing out different GC settings, but I
simply witched to a JRockit VM and all my memory problems were solved.
After doing some performance evaluations at my university I knew that
JRockit seems to handle its memory a lot more efficient than the Sun
VM (both with default GC setting), so I didn't bother testing the
settings of the Sun VM. Maybe someone on this list has some hints to
getting the Sun VM to clean up its memory better.
Hope this helps anyone.

*Betreff:* Re: Memoryleaks in Cocoon 2.1.7?
Just for the records, i'm currently experiencing some out of memory
errors on a cocoon 2.1.8 using common blocks + forms + fop on two
machines (a developer machine running windows, and a gentoo server),
while with the same cocoon version and same application it does not
happen on other machines (ranging from ubuntu and gentoo developers
machines, and an ubuntu server). So I thought it was a platform
problem, not directly related with cocoon (so didn't even tried a
profiled run), but since the thread is open and i have two machines
showing random out of memory, let me know if i can check something to
make it clearer.

I have read your posts. The problem seems to be a different one.
We increased the memory assigned to tomcat and cocoon and successfully
increased the time between OutOfMemory errors. With 2GB of Memory the
application runs stable for about one week. I am now looking for the
leak itself and as I can see in the jconsole there is deffinitively a
leak. If I cant get a tip here, my next step is to setup a profiler
and run jmeter stresstests untill I find the bug. Hopefully it is no
"big-one" in cocoon itself.
I would be VERY THANKFULL if you let me know if you find that leak.
