And if you look at screenshot you will see that garbage collecter can't free session memory because KnoledgeBase is referencing those sessions, not Main method. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/640362#640362] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
