Hmmm....
I am trying to find out more details using jmap and now I am no
more thinking that birt is the issue.
Adam, is it possible that the Webslinger component is causing this?
Running jmap -permstat I get the following stats:
Not the component, no. What you see below is a consequence of the
custom classes that get compiled for every single service engine
definition, so that you can see what file/line the service is
defined in.
sorry for the silly question: are you saying that the custom classes
are not compiled by some code in Webslinger? I really don't know
where to look for AsmUtil and GeneratedClassLoader.
I never said any such thing. I'm just saying that we may need more
permgen space, as that is where classes are loaded.
A while back in another thread you balked at the idea of having to
increase the memory settings to get OFBiz to run. Isn't memory
consumption a concern? If it is, do you have any insights into any ways
we could tackle this particular problem in a memory-reducing way? Or are
you certain the only solution is to change the settings to allow for
more memory?
I can only reduce the memory usage so much. As some point, we'll just
have to increase the memory allocation.
I don't have time right now to look into this in detail; I will do so,
just not right now. Debugging memory utilization is a hard thing to
do, as enabling the correct startup options makes java run *very* much
slower. Not to mention doing a jmap -dump, then looking at the output
with jhat and ibm heap analyzer is complex.
Keep in mind you're not alone. I can help if you can point me in the
right direction - that is, if you think it would be a worthwhile effort.
