Bug Description
This MAY be a duplicate of 1364840, but line number and stack trace show some differences :
2014-09-22 15:55:09 7f6ef08e0700 InnoDB: Assertion failure in thread 140114458969856 in file lock0lock.cc line 3980
InnoDB: Failing assertion: lock != ctx->wait_lock
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://
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
InnoDB: http://
InnoDB: about forcing recovery.
15:55:09 UTC - mysqld got signal 6 ;
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:/
key_buffer_
read_buffer_
max_used_
max_threads=1002
thread_count=197
connection_
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
