Hi,
I upgrade to latest version of django. Every time I navigate to django
admin site "User" page. I got this error:

DatabaseError: Lost connection to MySQL server at '.........', system

I debug the code:
I found every time executing this sql 'SELECT `auth_group`.`id`,
`auth_group`.`name` FROM `auth_group`, this error will occur.
