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
