Public bug reported: Running mydumper causes:
root@mysql:/home/supervisor# mydumper -B gitlabhq_production ** (mydumper:15451): CRITICAL **: Failed to connect to database: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111) root@mysql:/home/supervisor# MySQL error log: 2014-08-25 18:29:54 1438 [Note] WSREP: Provider paused at 87720985-2c49-11e4-948d-4a356f963e28:270 (3) 15:29:54 UTC - mysqld got signal 11 ; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail.
