Hi, One of the members of the custer crashed unexpectedly. Log file as follows: …… 131124 5:28:14 [Note] WSREP: (a89f58b5-3fc0-11e3-88e2-42a6d4c067ed, ‘ssl://0.0.0.0:4567’) turning message relay requesting on, nonlive peers: ssl://192.168.133.137:4567 05:28:14 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. Please help us make Percona Server better by reporting any bugs at [url][System Dashboard - Percona JIRA](http://bugs.percona.com/%5B/url%5D) key\_buffer\_size=8388608 read\_buffer\_size=131072 max\_used\_connections=13 max\_threads=153 thread\_count=2 connection\_count=2 It is possible that mysqld could use up to key\_buffer\_size + (read\_buffer\_size + sort\_buffer\_size)\*max\_threads = 343054 K bytes of memory Hope that’s ok; if not, decrease some variables in the equation.
