LP #1524895: All nodes crashed with signal 11

**Reported in Launchpad by Edward N last update 11-07-2017 04:18:52

Nodes:
Red Hat Enterprise Linux Server release 6.7 (Santiago)

Percona XtraDB Cluster (GPL), Release rel70.1, Revision 938, WSREP version 25.8, wsrep_25.8.r4150
wsrep_provider Galera 3.8(rf6147dd)

3-node cluster

All nodes suddenly crashed with 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 XtraDB Cluster better by reporting any
bugs at https://bugs.launchpad.net/percona-xtradb-cluster

It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 307222699 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
