2. Then mysqladmin shutdown
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=8388600 read_buffer_size=131072 max_used_connections=0 max_connections=100 threads_connected=0 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 225791 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=0xbfffd678, backtrace may not be correct. Stack range sanity check OK, backtrace follows: 0x80cedda 0x40078a65 0x40044237 0x4001fc31 0x4002010d 0x40021a24 0x4002d34e 0x4000df32 0x4020053b 0x401978b6 0x7fbd309 0x401955d6 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.
Thanks, Vadim. Is MySQL already running when you invoke this vtl command? Call Graph is a very intrusive form of profiling data collection. It literally modifies the binary prior to running it. You typically cannot use Call Graph on daemons, and definitely not on kernel modules.
