[stack] 110814 11:33:57 - 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. 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=2097152 max_used_connections=71 max_connections=400 threads_connected=3 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 2850816 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=0xa9663d0 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=0x92f38848, backtrace may not be correct. Stack range sanity check OK, backtrace follows: 0x8182ac5 0x4d47f2 0x51d701 0x5543ab 0x55c6c5 0x55cb09 0x83fcd53 0x81cd9c4 0x81c70db 0x81c8774 0x81c8fe0 0x81c91c7 0x826b863 0x81a24fc 0x81a31ff 0x65a832 0x5c546e New value of fp=(nil) failed sanity check, terminating stack trace! 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 0x938a7ff0 is invalid pointer thd->thread_id=781 The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains information that should help you find out what is causing the crash.
