MySQL server has gone away

[anonymous]

I get this traceback even though the MySQL server is happy. The only recourse is to restart the trac server. Maybe it is some kind of connection caching? It should be possible to catch this and reconnect. There is also a MySQL auto reconnect option, although I have never used it. Thanks!
