Description

1. message dispatcher trying to send a reAuth message to the client, but not able to because the socket buffer is full.
2. client updater is blocked waiting for a regionEntry lock when doing a remove operation.
3. the regionEntry lock is held by a client operation doing destroy on that same key
4. the client operation is waiting for the re_auth op to finish.
5. the re_auth command on the server is blocked by the #1 holding the lock
