Server errors –ID 2009

I have a server error that keeps occuring. It keeps going over and over every 1 minute until it fills the maximum size of the event viewer. It says “the server could not expand a table because the table reached the maximum size.” The event ID is 2009. I looked it up on Technet and it said to modify some registry values. I did that and it still is having the same error. Does anyone have some idea of how to fix this?
