‘mysqld got signal 11’

 

It is not clear what caused this, but this is how it was fixed – eventually!  The main issue that resulted from the failure was that the database would not restart and there were 1000's of relay log files in the $DATADIR

 

• Killed all mysql processes and mysqld processes – had to use kill -9 for mysqld process

 

• Removed all relay bin logs from $DATADIR

 

• Restarted mysql using /usr/local/mysql/bin/mysqld_safe &

 

• Stopped slave

 

• Systems team stop mail

 

• Recreated slave from master (oook)

 

• Connect to database and issue 'flush logs'

 

• Set master log file and llog file position

 

• Restart slave

 

Everything should be working now!
