    Description

      Right now network connections aren't re-established in case of connection loss. New cluster management API depends on this capability b/c the services are restarted by systemd in case of a crash.

      There are different kind of network connections used by network services some of them must be re-established(DMLProc/DDLProc -> WriteEngine) some not (ExeMgr -> PrimProc).

          All connections, even ExeMgr<->PrimProc should be re-establised if one process goes down. THe industry standard way of dealing with this is to use heartbeat (or stay-alive) messages.
