To enable this  fix, set event 44951 to the maximum number of chunks that you would like  to have reclaimed per attempt. The maximum allowed is 1024. Anything  larger becomes 1024. However, if the requested amount of space is larger  than the event’s value, the reclaim will be for the requested amount of  space. Good luck! -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/623786#623786] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
