To answer Martin's question:
This is in a production environment.   There isn't any hot deploying
happening.  

Our production environment virtual machine args: 
-Xms128m -Xmx1024m -Dorg.apache.tapestry.disable-caching=false
-XX:MaxPermSize=128m 

I don't know how much larger the PermSize can be.  

Thanks for your help.

Subject: Re: PermGen space - Caching is ON

Just an idea: could it be that some aspectizing container (Spring or
HiveMind)has a not quite correctly written service that is not a
singleton, but a (bad) factory. That factory might create new aspectized
class every time and then instantiate object instead of creating a
weaved class once and then creating objects from it. That would clog
PermGen space.

Do you run anything non-standard or suspicious?
