It seems is caused because MySQL close the connection after 8 hours, this time is stored at 'wait_timeout' system variable in the MySQL server. I'm doing an application for school where isn't there activity at night. Given that mysql (or any other database) may well be restarted as part of log rotation and cron maintenance, you may well want to not depend on continuously open connections.

I'm doing an application for school where isn't there activity at night. Then db.py don't know this because it feels that connection is alive. Maybe the solution is check the connection before db.query. Very easy to create a simple DTML routine which accesses MySQL; then set up a cron job to run that DTML routine every few hours.
