Subject [jira] [Created] (DIRSERVER-1760) When one of the server disconnect brutally, replication stops working
Date Fri, 09 Nov 2012 16:28:12 GMT
Emmanuel Lecharny created DIRSERVER-1760:
--------------------------------------------

             Summary: When one of the server disconnect brutally, replication stops working
                 Key: DIRSERVER-1760
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1760
             Project: Directory ApacheDS
          Issue Type: Bug
    Affects Versions: 2.0.0-M9
            Reporter: Emmanuel Lecharny
             Fix For: 2.0.0-M9


If we unplug the network cable, the replication does not work anymore, even if we replug the
cable. The disconnection is detected if we update the local server, but we never retry to
connect again :

I'm also afraid that we won't be able to detect such a disconnection if it occurs, as the
network layer won't be informed about it.
