Subject [Mostly OT] Sweeping the permgen space: is that a good thing?
Date Mon, 13 Dec 2010 10:13:53 GMT

I know that my problem is with the application my tomcat 5.5 powered by
java 1.5.0_b4 is running.

I have this supposely leeking application that keeps saturating the
permanent generation.

The problem is an out of memory on the permgen.

Studying the JVM, i understand that the permgen is never sweeped by GC.

My question is: i found the flags combo that enables permgen sweeping.
Is that a good thing to enable? I can't fix the application right now.

Thanks very much.
