[jgroups-dev] jgroups node joining stopped working on infiniband network

We are using jgroups-3.2.4.Final version for a 90 plus nodes cluster.
Its been afew years of successful run on ethernet based network.
However it started failing once migrated to an inifiniband based network
architecture.

Additional FRAG layer has been added in the udp-largecluster.xml to restrict
data size to 3072 which doesn't solve the problem.
No errors are encountered, the jchannel.connect call hangs forever.

uploaded logs indicating such a scenario and its observed that no
coordinator has been found....
Please help trouble shoot the issue. jgroups.txt
