             Summary: Broker listener takes a long time to shut down on cluster stop/restart
                 Key: BIT-1522
                 URL: https://bro-tracker.atlassian.net/browse/BIT-1522
             Project: Bro Issue Tracker
          Issue Type: Problem
          Components: Broker
    Affects Versions: 2.4
         Environment: Ubuntu 14.04, Bro 2.4.1 with Broker
            Reporter: Stephen Hosom 


It looks like when shutting down Broker, the listener sticks around for an exceptionally long time (as much as a minute or more). Because of this, Broker's listener actually fails to re-bind to the port on the next cluster start silently. All Broker communication then fails to work silently. It can take a while to notice this failure, since nothing really complains. 

The listener should probably shut down faster than 1 minute... but it might also make sense to add options to have the listener retry to start, or generate a failure message when it doesn't start. Maybe listener starts in bro_init should actually cause Bro to stop, so that the user sees the failure immediately?
