Hello Atin,
I just read it and very happy you found the issue. We really hope this will be fixed in the next 3.10.7 version!
PS: Wow nice all that c code and those "goto out" statements (not always considered clean but the best way often I think). Can remember the days I wrote kernel drivers myself in c :)
Regards
Jo Goossens

We use glusterfs 3.10.5 on Debian 9.
When we stop or restart the service, e.g.: service glusterfs-server restart
We see that the wrong port get's advertised afterwards. For example:
Before restart:

They try to reach it on the "new" port instead of the old one:[2017-09-21 08:33:25.225006] E [socket.c:2327:socket_connect_finish] 0-public-client-2: connection to 192.168.140.43:49154 failed (Connection refused); disconnecting socket[2017-09-21 08:33:29.226633] I [rpc-clnt.c:2000:rpc_clnt_reconfig] 0-public-client-2: changing port to 49154 (from 0)[2017-09-21 08:33:29.227490] E [socket.c:2327:socket_connect_finish] 0-public-client-2: connection to 192.168.140.43:49154 failed (Connection refused); disconnecting socket[2017-09-21 08:33:33.225849] I [rpc-clnt.c:2000:rpc_clnt_reconfig] 0-public-client-2: changing port to 49154 (from 0)[2017-09-21 08:33:33.236395] E [socket.c:2327:socket_connect_finish] 0-public-client-2: connection to 192.168.140.43:49154 failed (Connection refused); disconnecting socket[2017-09-21 08:33:37.225095] I [rpc-clnt.c:2000:rpc_clnt_reconfig] 0-public-client-2: changing port to 49154 (from 0)[2017-09-21 08:33:37.225628] E [socket.c:2327:socket_connect_finish] 0-public-client-2: connection to 192.168.140.43:49154 failed (Connection refused); disconnecting socket[2017-09-21 08:33:41.225805] I [rpc-clnt.c:2000:rpc_clnt_reconfig] 0-public-client-2: changing port to 49154 (from 0)[2017-09-21 08:33:41.226440] E [socket.c:2327:socket_connect_finish] 0-public-client-2: connection to 192.168.140.43:49154 failed (Connection refused); disconnecting socketSo they now try 49154 instead of the old 49152Is this also by design? We had a lot of issues because of this recently. We don't understand why it starts advertising a completely wrong port after stop/start.
