070217 18:32:26 [Note] /home/sbester/server/5.0/mysql-5.0.36-linux-i686/bin/mysqld: ready for connections. Version: '5.0.36-debug' socket: '/tmp/mysql.sock' port: 3307 yes 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=8388572 read_buffer_size=131072 max_used_connections=1 max_connections=100 threads_connected=2 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 225788 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. thd=0x8beca28 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...
