We are using Jboss4.2.2 JBM 1.4.2 sp1. publish persistent 50,0000 msg | publisher.publish(objMsg, DeliveryMode.PERSISTENT, PRIORITY,0); | All msg subscriber are Nondurable subscriber. Due to some subscriber are very slow,jmx console show depth are increasing.And we fount the count of JBM_MSG&JBM_MSG_REF are increasing too. After rebooting JBM and client,the new client begin to consume old messages in db. Why? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4220007#...
