| 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). |

You imply we do not want automatic reconnection between ExeMgr and PrimProc. If this is your intent, I think perhaps we need to have these reconnect automatically. |

We'll see if this is necessary for v2. At least in v1 (1.5.4 release) it's not b/c we restart everything on every node when there is a node-up/down event. |
