I usually see Sort aborted messages when mysqld crashes. If mysqld is still running, it was probably restarted by mysqld_safe. It could also comes about witha manual restart of mysql.

You should look below those lines to see if MySQL was restarted with the phrase 'ready for connections'

The Sort aborted messages could also have come about from a mass killing of DB Connections that were busy executing SQL queries.
