I have now applied patch for #1032 ontop of 4.6 changeset **5969:ead18326c13b**.
[devel] [PATCH 1 of 1] mds: use correct buff-length to distinguish mcast or
multi-unicast [#1036]
This patch does **not** resolve the problem.
SC-1 immnd get the TRY_AGAIN message with to many outstanding messages.
PL-3 - PL-6 joins without problems.
PL-7; which is the node causing this condition have following entries in the
trace log:

** [tickets:#1072] Sync stop after few payload nodes joining the cluster (TCP)**
**Status:** unassigned
**Milestone:** 4.3.3
**Created:** Fri Sep 12, 2014 09:20 PM UTC by Adrian Szwej
**Last Updated:** Thu Sep 18, 2014 06:27 PM UTC
**Owner:** nobody
Communication is MDS over TCP. Cluster 2+3; where scenario is
Start SCs; start 1 payload; wait for sync; start second payload; wait for sync;
start 3rd payload. Third one fails; or sometimes it might be forth.
There is problem of getting more than 2/3 payloads synchronized due to a
consistent way of triggering a bug.
The following is triggered in the loading immnd causing the joined node to
timeout/fail to start up.
