From the mysql.err:
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=2097152000
read_buffer_size=2093056
max_used_connections=36
max_connections=300
threads_connected=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 3275597 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Number of processes running now: 0
------
There is no backtrace.
How to repeat:
Optimize an old format table
Suggested fix:
workaround: don't use old isam tables.
