Message groups interleaving

Hi, Having multiple message groups producers and multiple async consumers, would it be correct to anticipate that a single consumer may get the messages received being interleaved from different groups of messages? Example: - msg producer P1 sends a group of 2 msgs: P1.1 and P1.2, while at the sa

Re: Java app hanging at createTemporaryQueue

Hi, are you using failover-transport? If yes, you'll need to add a "timeout" parameter to the connection URL, as the default behavior of the failover transport is to wait indefinitely for a reconnect to the broker. Please see http://activemq.apache.org/failover-transport-reference.html for further
