[jira] Created: (AMQ-1173) MulticastDiscoveryAgent heart beast may stop of machine clock jumps around.

MulticastDiscoveryAgent heart beast may stop of machine clock jumps around.
---------------------------------------------------------------------------

                 Key: AMQ-1173
                 URL: https://issues.apache.org/activemq/browse/AMQ-1173
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 4.1.0
            Reporter: Hiram Chirino
         Assigned To: Hiram Chirino
             Fix For: 4.1.1


Surprisingly, many high end machines now days have a hard time keeping a consistent clock.  The clocks may run fast and user tend to use a periodic cron job to sync the time on the local machine to the correct time.  When this happens the time looks like it went backwards and this was delaying the sending of Mutlicast heartbeats.
