问题
I have a series of python scripts that are designed to be long running. When I look at the MySQL process monitor, I see that three of them will always have a time of 0, then 2 of them that I use to actually insert data into the database will have values that are always counting up, and never get reset to 0 meaning that eventually they encounter the dreaded 'MySQL has gone away'.
I am using MySQLdb.
Can someone please explain why this happens?
Is there a way to make sure that they reset this value to 0?
Thanks

It sounds like your idle timeout is expiring. This is set in the mysqld server configuration, though, and is not really an issue with MySQLdb. You need to adjust the wait-timeout system variable, either in the server configuration, or with an SQL statement when you connect.
