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=402653184 read_buffer_size=4190208 sort_buffer_size=1919252082 max_used_connections=0 max_connections=650 threads_connected=0 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 785799 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=0x8448fe8 Attempting backtrace.
