Hi Tim, You must have changed the fullSize parameter for your destination No, I haven't change the fullSize parameter. I have upgrade to SP1 and the nightmare persist: If I send fullSize + downCacheSize - 1 messages to a queue (*without consumers) then this queue will not be deployed at next boot. The test has been performed using a fresh instalation of JBAS 4.2.1.GA and JBM 1.4.0.SP1 with PostgreSQL in a non-clustered environment. I have used the '/queue/testQueue' destination (a test queue deployed in default destination-services.xml) and I have send 200100 messages (1K each one). But the problem.....persist. Any help will be wellcome, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4101895#...
