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=10485760 read_buffer_size=8384512 max_used_connections=2000 max_connections=2000 threads_connected=1166 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 32770224 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.
