             Summary: Introduce a heartbeat mechanism for v0 executor <-> agent links.
                 Key: MESOS-7568
                 URL: https://issues.apache.org/jira/browse/MESOS-7568
             Project: Mesos
          Issue Type: Bug
            Reporter: Anand Mazumdar


Currently, we do not have heartbeats for executor <-> agent communication. This is especially problematic in scenarios when IPFilters are enabled since the default conntrack keep alive timeout is 5 days. When that timeout elapses, the executor doesn't get notified via a socket disconnection when the agent process restarts. The executor would then get killed if it doesn't re-register when the agent recovery process is completed.

Enabling application level heartbeats or TCP KeepAlive's can be a possible way for fixing this issue.
