Hi Oleg,

 

we encountered similar problems and = fortunately found our that these problems were VM related. I assume you are using a = standard Sun JDK installation (This was the case with our system). When looking at = the VM memory consumption, we could see an increasing memory consumption. Whenever we manually triggered a “big garbage-collection” most of this = was freed again. The problem is that the default Garbage Collection Settings = seem to have problems with circular references. Memory, which is not = accessible, is not freed because of this. We could have solved this by tweaking the GC settings of the VM, but we got rid of the problems by using the BEA = Jrockit VM instead (I knew this would work and I didn’t want to dig into all = the switches an leavers of the sun GC)

 

Hope this helps.

Hi,

We are getting OutOfMemoryError
16:26:41,011 ERROR [STDERR] java.lang.OutOfMemoryError
in our production server (which has 4GB of RAM, javaVM - max 2GB)
every other day. All applications stop responding.
We have a bunch of Cocoon applications [mostly 2.0.4] running on = JBoss3.0.7.
It is totally unclear which application is causing the problem.

I don't remember that problem happening in our Development or Testing environment
(where max JavaVM=3D512MB), but I guess it has a much lighter load.

Is there any known memory problem with Cocoon ?

Is there a way to do memory profiling of Cocoon Apps ? Any particular = tool ?
(I have done memory profiling of Java applets with JProbe years = ago)

 
Any advice is very appreciated.

Thank you in advance,
 Oleg.
