After having two clients running FLUSH TABLES WITH READ LOCK/UNLOCK TABLES against Galera node, the node sometimes gets stuck in paused state causing following queries to fail, e.g.
ER_UNKNOWN_COM_ERROR (1047): Aborting TOI: Replication paused on node for FTWRL/BACKUP STAGE.
The attached patch contains required sync points and a test case to reproduce the problem.
