permGen Space
I will appreciate if anybody could assist with how I can get to the root
cause of a permGen Space error that comes at atimes for me. At this
instance see the dump below:

That will only affect Netbeans itself, not the tomcat server your
application runs on, which is where the problem is. In Netbeans, right
click the Tomcat node, select Properties and add whatever options you
want (without -J) on the VM Options field in the Platform tab, then stop
tomcat and restart it.

many thanks,
I am using netbeans IDE and have updated netbeans.conf file in my home user
netbeans/6.1/etc folder as follows:
-J-Xss2m -J-Xms32m -J-XX:PermSize=64m -J-XX:MaxPermSize=1024m
the problems still persists after some building & re-deployment iterations.
whenever netbeans output Final Memory: 51M/104M shortly after that I'll get
this weird behaviour.
Is the Final Memory statistics that netbeans output as the last entries
during a build / run process related to the MaxPermSize? Is there anything
I am missing above?
Cheers

FYI PermGen space is the space used to hold classes. IN an app server
you often need more than the normal amount, since there is so much
extra code. Tapestry itself adds many dependencies, plus extra class
loaders, plus many runtime-generated classes. More PermGen space is a
good idea.

Try raising the permgen space maximum allocated memory.
