mysql slave crashes
Posted by: Ilya Antipov

Today I started a slave. Everything went ok, but after a few hours slave began to restarting constantly.
Error log has the following string

06:59:49 UTC - 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=1468006400
read_buffer_size=131072
max_used_connections=3
max_threads=230
thread_count=1
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1936701 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

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...

And this repeats over and over again.

Maybye this would be helpfull. To me it's not a problem right now - I will recreate my slave, but i Believe it's a bug. I will copy the database files - so if needed I can give them.

Thanks
