Hi, we have tested ActiveMQ 4.0.2 for a long time on a network without firewall between clients and broker. Switching to DMZ with firewalls we stumbled across problems with activemq connections. It appears that whenever firewall closes connection, activemq doesn't, which eventually leads to OutOfMemoryError (not every time). We've set Java's max memory to 512MB and every 1hour we get activemq to freeze, ie. it works but doesn't send any message neither clients can connect to it. All we can do is to restart it. We have increased memory limits however I'm not sure if that helps. Has anyone successfully managed to setup activemq broker inside DMZ with firewalls between clients and broker ? -- View this message in context: http://www.nabble.com/ActiveMQ-4.0.2-errors-with-firewall-between-client-and-broker-tf4508844s2354.html#a12858780 Sent from the ActiveMQ - User mailing list archive at Nabble.com.
