    Description

      The Galera cluster locked up on one of the nodes. After this node was restarted, the rest of the cluster was unlocked. While it have happened with Galera, it feels more of MariaDB problem than a Galera problem.

      Log from the affected node and config is attached (other nodes don't have anything interesting in the logs and the config is exactly the same).

            hi Jan,

            We hit the same error messages in production and the db froze (percona 5.5.33)
            can you provide more details on the reason for the freeze and fix ?

            our scenario was that we had very high writes (blob inserts) and high reads (blob reads) on the db.

            also could you shed some light on the message "Mutex at 0x2af53fbfc138 '&kernel_mutex'" --> what exactly is the kernel mutex ?

            thanks,
            ch Vishnu
