ERROR 2013 (HY000): Lost connection to MySQL server at 'reading authorization packet', system error: 0

Question

I am getting the following error

ERROR 2013 (HY000): Lost connection to MySQL server at 
\'reading authorization packet\', system error: 0

Answer 1

I solved this by stopping mysql several times.

$ mysql.server stop
Shutting down MySQL
.. ERROR! The server quit without updating PID file (/usr/local/var/mysql/xxx.local.pid).
$ mysql.server stop
Shutting down MySQL
.. SUCCESS! 
$ mysql.server stop
ERROR! MySQL server PID file could not be found! (note: this is good)
$ mysql.server start

All good from here. I suspect mysql had been started more than once.
