MySQL: Can't create/write to file '/tmp/#sql_3c6_0.MYI' (Errcode: 2) - What does it even mean?

Question

For some reason my production DB decided to spew out this message. All application calls fail to the DB with the error:

PreparedStatementCallback; SQL [ /*lo         


        

Answer 1

A better way worked for me.

    chown root:root /tmp
  chmod 1777 /tmp
  /etc/init.d/mysqld restart

That is it.
