AW: Memoryleaks in Cocoon 2.1.7?

[Christofer Dutz]

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.   Chris   Von: Simone Gianni [mailto:[EMAIL PROTECTED] Gesendet: Donnerstag, 2.

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.

The problem seems to be a different one. We increased the memory assigned to tomcat and cocoon and successfullyincreased the time between OutOfMemory errors. With 2GB of Memory theapplication runs stable for about one week. I am now looking for theleak itself and as I can see in the jconsole there is deffinitively aleak. If I cant get a tip here, my next step is to setup a profilerand 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.   -- Simone Gianni
