This patch is not related to `TCP` this exclusively for `TIPC` ,
Please provide following , for me to reproduce the problem :
1. Reproducible steps
2. dtmd.conf file
3. imm.xml configuration details ( it seems you preperaed 70 node
configuration )
4. You system buffers info ,check below link to get the data of your nodes:

** [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:** Wed Oct 01, 2014 06:39 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.

I have managed to overcome this bug temporary by making following patch:
