> 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.
