Please tell me if you need more information.
Thanks,

2014-10-08 03:10:49 7fffedd97700 InnoDB: Assertion failure in thread 140737183840000 in file row0upd.cc line 442
|
InnoDB: Failing assertion: foreign->referenced_table ->n_foreign_key_checks_running > 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
|
InnoDB: http://dev.mysql.com/doc/refman/5.6/en/forcing-innodb-recovery.html

|
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.
|
|
|
To report this bug, see http://kb.askmonty.org/en/reporting-bugs
|
|
|
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: 10.0.12-MariaDB-wsrep
|
key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=45
|
max_threads=1026
|
thread_count=27
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 2385333 K bytes of memory
|
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...
