Memory leak testing

There is still a memory leak in the mining servers that I've been investigating for about a week. It does not occur in development and the only way to figure this one out is to restart one of the mining servers a few times throughout the day. About 1/8 of miners will be disconnected a few times today.

We need to figure this bug out because otherwise people are going to get disconnected anyway when the servers run out of memory. I apologize for the issue, but the disconnects will only last for a few seconds.
