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=8388572 read_buffer_size=131072 max_used_connections=1 max_connections=100 threads_connected=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 225788 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=0x8e40b20 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... Cannot determine thread, fp=0x4d11febc, backtrace may not be correct. Stack range sanity check OK, backtrace follows: 0x81d6c8b 0xffffe420 Stack trace seems successful - bottom reached Please read http://dev.mysql.com/doc/mysql/en/Using_stack_trace.html and follow instructions on how to resolve the stack trace. Resolved stack trace is much more helpful in diagnosing the problem, so please do resolve it Trying to get some variables. Some pointers may be invalid and cause the dump to abort... thd->query at 0x8e702a8 = select x into x thd->thread_id=1 The manual page at http://www.mysql.com/doc/en/Crashing.html contains information that should help you find out what is causing the crash.
