Bug Description
2 Galera nodes on 1 server with 2 interfaces on port 3306
node 1 starts properly (gcomm://)
when node 2 starts node 1 falls into state initialized/
This seems to be related somehow to SST (mysqldump).

Similar case reported in https:/
It appears that if gmcast.listen_addr is configured to certain address, local connection point for outgoing connections is not bound to listen address. If OS has multiple interfaces with IP addresses in the same subnet, it may happen that OS picks wrong IP for local connection point and other nodes see connections originating from IP address which is not listened to.
