Description:
Server mysqld got signal 11 and crashed itself;
Extract from mysqld.log
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=536870912
read_buffer_size=10485760
max_used_connections=17
max_threads=40
thread_count=6
connection_count=6
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1917409 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...

Trying to get some variables.
Some pointers may be invalid and cause the dump to abort.
Query (0x7f6c58192040): is an invalid pointer
Connection ID (thread ID): 628
Status: NOT_KILLED
How to repeat:
It occurs occasionaly and dont know what caused the crash , so cannot manually to cause it to crash.
Check tables show all tables ok
