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=0xb4f67488, backtrace may not be correct. Stack range sanity check OK, backtrace follows: 0x817de07 0xffffe420 0xb4f67828 0xb7d1bf8b 0xb7d21911 0xb7d22f84 0x83ef351 0x83ef931 0x819dc05 0x819f1b3 0x819fc1d 0xb7f3c34b 0xb7d7b65e 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.
