1. Re: PermGen Error during deployment or when application is running
wdfink Dec 15, 2010 2:18 AM (in response to amarbhat)The PermGenSize depends to your application and some other parameters.
There is no general answer, you have to analyse the behaviour.
Helpful starting point is the Java GC site http://www.oracle.com/technetwork/java/javase/gc-tuning-6-140523.html
From Peter Johnson is an article here http://www.cmg.org/cgi-bin/search.cgi?q=java+peter+johnson&x=30&y=10
If the problem is reproducable the java tools jconsole, visualgc, jstat or jhat are helpful. We use jProfiler at the moment, but there are also different Java profiling tools available.
