InnoDB: If you get repeated assertion failures or crashes, even

mysqld got signal 11;
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=0
read_buffer_size=8384512
max_used_connections=0
max_connections=4000
threads_connected=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 65519968 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
thd=(nil)
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...
frame pointer is NULL, did you compile with
-fomit-frame-pointer? Aborting backtrace!
The manual page at
http://www.mysql.com/doc/en/Crashing.html contains
information that should help you find out what is causing the crash.
