Roberto,
Please file a JIRA issue with your observations since we are making a
concerted effort to clean up Jetspeed's memory usage and footprint. It
would be a handy place to submit your graph to us. It would be most
helpful if you could do the same for 2.2 if you have time to test there
as well.
Also, please note that a cache reporting portlet has been added to
Jetspeed administrative pages so that you can examine the current cache
counts and memory usage. That is available in the latest version of
2.1.3 post branch and 2.2 trunk.
Thanks,
Randy

I'd like to share with you my personal Jetspeed 2.1.3 heap usage
analysis.
After Jetspeed startup (together with j2-admin web app and another our
internal web app), I found a strange heap usage graph (through JConsole)
even without no requests being processed.
The Heap starts from 40Mb about, then it increases regularly to 70Mb
about. At this point a PSYoungGen brings it back to 40Mb about.
This routine executes forever even if no requests are processed by the
portal.
Is it a normal Jetspeed behaviour or is it a particular issue?
In the past, I found another user talking about this issue but no one
explained him the reason (http://markmail.org/search/?q=jetspeed+idle
+heap#query:jetspeed%20idle%20heap+page:1+mid:qi2fgmsz2mw7lfw5
+state:results).
I can send you a png image showing this.
Roberto
