----------------------------------
[~kaysoky] is this still an issue for v0 executors?
> Introduce a heartbeat mechanism for v0 executor <-> agent links.

> URL: https://issues.apache.org/jira/browse/MESOS-7568
> Project: Mesos
> Issue Type: Bug
> Reporter: Anand Mazumdar
> Priority: Critical
> Labels: foundations, mesosphere
>
> 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.
