InnoDB: Submit a detailed bug report to http://bugs.mysql.com. InnoDB: If you get repeated assertion failures or crashes, even InnoDB: immediately after the mysqld startup, there may be InnoDB: corruption in the InnoDB tablespace. Please refer to InnoDB: http://dev.mysql.com/doc/mysql/en/Forcing_recovery.html InnoDB: about forcing recovery. mysqld got signal 11; 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=8388608 read_buffer_size=258048 max_used_connections=4 max_connections=510 threads_connected=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 658948 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=(nil) 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=0x7e3be8ac, backtrace may not be correct. Stack range sanity check OK, backtrace follows: 0x817b8f2 0x306888 0x314e 0x82e0dcf 0x82bb620 0x82bc8bb 0x8310a18 0x8337009 0x82a085a 0x300371 0xcd29be 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 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.
