06:23:02 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. Please help us make Percona Server better by reporting any bugs at http://bugs.percona.com/
key_buffer_size=8388608 read_buffer_size=131072 max_used_connections=19 max_threads=152 thread_count=16 connection_count=16 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 68309 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.
