    Message Expiry In Cluster

      Hi,

       

      I have two HornetQ instances in a symmetric cluster. The configuration files are attached. I have ExpiryQueue setup as the expiry address for ExampleQueue. When I send a message to ExampleQueue with an expiry of 1 sec (producer.setTimeToLive(1000)), I get the following exception in the log files of one of the clusters.

       

      [hornetq-expiry-reaper-thread] 17:22:18,378 SEVERE [org.hornetq.core.postoffice.impl.PostOfficeImpl]  failed to expire messages for queue jms.queue.ExampleQueue

      The message expiry works occasionally, but it gives the above exception most of the times. I'd like to create a test case to demonstrate this problem with some consistency, but I thought if someone can catch a glaring problem with my configuration, I thought I can save the trouble.
