TCP/IP?

I dont think its a virus but in my system log it states that my computer has reached its TCP/IP limit imposed on it yet I dont share on a network could this be virus activity trying to share stuff or is it something more harmless, any help is appreciated?

ps Avast reports nothing and neither does ad-aware.

If you can post the complete text of the message ?

What are you doing when this happens, Iā€™m guessing P2P ?
