Hi, I am the author of the issue you refer to your message http://www.mail-archive.com/jboss-user@lists.sourceforge.net/msg31913.html Back then i solved the problem by disabling the security manager interceptor of the JbossMQ implementation. Recently I moved to the Jboss messaging implementation and starting having the same problem (nightmare) again. I would like to ask if raising the DefaultCacheTimeout did solve the problem. Thanks.
