Problems with database and server
 

Hello,
Everything was working well until yesterday. For the past 3 days, users are complaining that the forum is too slow or not responding.

I keep receiving erros like this one every 10 minutes or so:

Is this a problem from my host (HostGator) or the database?

Please Help.
