User development, A new message was posted in the thread "Memory consumption 1h after JBoss start": http://community.jboss.org/message/521686#521686 Author : Giovanni Formenti Profile : http://community.jboss.org/people/formenti Message: -------------------------------------------------------------- Hi Peter, I used Eclipse MAT (a great tools IMHO!) and also JProfiler. This is the difference between the memory after 50min and 63min (the peak is around 60min). http://community.jboss.org/servlet/JiveServlet/showImage/1829/heap2.JPG I trace the GC also and I notice a strange behavior of Survivor Space when the GC begin its intensive activity (after 1h). It seems that it exceeded the maximum: http://community.jboss.org/servlet/JiveServlet/showImage/1830/heap3.JPG Exploring the memory dump, the Maps and ZipEntries seem to be related to MBean map and deploy/vfs structures. Their shortest path to GC root involve http-0.0.0.0-8080 threads. This could be related to connection pools or aliveness of connections?   Thank you for any tips about this Regards   Giovanni -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/521686#521686
