RHEL Linux 2.6.32-431.11.2.el6.x86_64
Description
The Galera cluster consists of 2 data nodes and one Galera Arbitrator.
The cluster has been up and running with 10.0.14 since "141105 5:41:15"
141116 0:51:17 [ERROR] 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.

|
Server version: 10.0.14-MariaDB-wsrep-log
|
key_buffer_size=57671680
|
read_buffer_size=65536
|
max_used_connections=113
|
max_threads=501
|
thread_count=45
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 238333 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

terribly wrong...

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains

information that should help you find out what is causing the crash.

141116 00:51:25 mysqld_safe WSREP: not restarting wsrep node automatically
|
141116 00:51:25 mysqld_safe mysqld from pid file /data/lib/mysql/SESAMMALSQL02.pid ended

The crashed node was kept down for memory chips check.
After the crash, the only live Galera node started time to time to respond to the application with Primary key duplicate errors.
Due to that error, a decision for restarting the garbd instance has been taken.
On the garbd stop the only node lost the quorum and refused new connections, so had to be restarted with bootstrapping a new cluster.
