03:00:01 UTC - mysqld got signal 6 ;
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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.

key_buffer_size=524288000
read_buffer_size=16777216
max_used_connections=71
max_threads=5000
thread_count=22
connection_count=15
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 164418796 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
