vb.org Archive - MySQL server has gone away

Hey guys,

I'm getting repeated MySQL errors all of the sudden and I don't know what changed that's causing it.

This one is the most popular and will occur about 5-6 times a day:

The first one - MySQL has gone away - is the more prevalent of the errors. Every time I get an error, though, it's always for class_core.php on line 311. Is a timeout that I have set too short or is there a firewall issue or what?
