If persistence is used, and a node is marked down and then up in quick succession (less than about 7 seconds), then persistence may act inconsistently.
Persistence may act inconsistently (meaning, not all connections expected to persist to a server will do so). In certain circumstances, requests may hang (the client is connected, waiting for a response).
Persistence, rapid node flapping, new connection (via a TMM with an existing connection) after node has been re-marked as up.
None.
The system now deletes a persist entry from all peer TMMs when it is deleted in any TMM, so no conflicts occur.
