Public bug reported:
Description
==================
After deploying three three nodes inside LXC containers on ppc64, two eventually
die off with the below after some time:
161203 1:23:32 [Note] WSREP: Quorum results:

fil0fil.c line 5288
InnoDB: Failing assertion: node->n_pending > 0
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to

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
key_buffer_size=33554432
read_buffer_size=131072
max_used_connections=423
max_threads=3002
thread_count=422
connection_count=422
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 6603710 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went
terribly wrong...
