Description:
MySQL database crashed. The error log can find below,
090820 3:18:54 InnoDB: Assertion failure in thread 1076947264 in file row/row0mysql.c line 1534
InnoDB: Failing assertion: index->type & DICT_CLUSTERED
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/5.1/en/forcing-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=268435456
read_buffer_size=1048576
max_used_connections=20
max_threads=500
threads_connected=19
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1803233 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

How to prevent the database crash?
How to repeat:
I cannot recreate the issue because MySQL having production databases.
