             Summary: Libprocess doesn't handle IP changes
                 Key: MESOS-7698
                 URL: https://issues.apache.org/jira/browse/MESOS-7698
             Project: Mesos
          Issue Type: Bug
          Components: libprocess
    Affects Versions: 1.2.0
            Reporter: Ilya Pronin


If a host IP address changes libprocess will never learn about it and will 
continue to send messages "from" the old IP.

This will cause weird situations. E.g. an agent will indefinitely try to 
reregister with a master pretending that it can be reached by an old IP. The 
master will send {{SlaveReregisteredMessage}} to the wrong host (potentially a 
different agent), using an IP from the {{User-Agent: libprocess/*}} header.
