key_buffer_size=12582912
read_buffer_size=131072
max_used_connections=27
max_threads=502
thread_count=12
connection_count=12
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 212606 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...
