In war3ft 3.0 MySQL sometimes throws the error "MySQL server has gone away". You can see more information in this thread:

I'm really not sure what to do in order to fix this - when googling it it just says that the connection has timed out, which takes 8 hours... Which is a little confusing as I never had this problem in a previous version of war3ft which didn't use threading. Did threading introduce something new that I need to be aware of?
I was thinking maybe the connection isn't closed/re-opened on map change, so it times out after 8 hours or something? I have no idea. Any advice would be greatly appreciated. You can view the MySQL code
here.
Thanks!
