5.5.16版，Assertion failure in thread *** in file rem0rec.c line 561

5.5.16版，运行了好久了。最近二周，数据库自动重启了二次，请大家帮着分析下，内存是够用的.InnoDB: Submit a detailed bug report to http://bugs.mysql.com130705 12:22:02  InnoDB: Assertion failure in thread 140205856859904 in file rem0rec.c line 561
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=536870912
read_buffer_size=2097152
max_used_connections=14
max_threads=2048
thread_count=5

It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 13130464 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.Thread pointer: 0x7f754c000990
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...
