Description:
Hi,
MySQL began to crash every 5-6 days on similar queries last 3 times.
The query executes frequently so it's not a cause of crashes itself.
InnoDB: Error: MySQL is trying to perform a consistent read
InnoDB: but the read view is not assigned!
TRANSACTION 1E1794A2E6, ACTIVE 0 sec fetching rows, thread declared inside InnoDB 500

150908 10:32:57 InnoDB: Assertion failure in thread 139774129370880 in file row0sel.c line 3862
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/5.5/en/forcing-innodb-recovery.html
InnoDB: about forcing recovery.

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.
key_buffer_size=6442450944
read_buffer_size=131072
max_used_connections=312
max_threads=250
thread_count=85
connection_count=85
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 6839175 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...
