    I can`t find why my MySQL crashing every day few times with signal 11 error, I hope so that somebody of you know how I can fix this...
    This is on Dual Opteron server with Centos 4.2 64 bit...

    This is error:
    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=19922944
    read_buffer_size=2093056
    max_used_connections=7
    max_connections=1300
    threads_connected=6
    It is possible that mysqld could use up to
    key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 533904
    5 K
    bytes of memory
    Hope that's ok; if not, decrease some variables in the equation.

    Have you figured your problem out? What was the fix?

    Similar problems here, using CentOS (32 Bit) + MySQL 4.1.22
