Question : Router Sessions

How can I tell if router sessions in my router's logs are something I need to be concerned about? There is one system of concern and it has had nearly 10,000 sessions to various IPs (now in an inactive state) and the session log is "filling up" every 15-30 min (to 512MB) indicating consistent activity.

Most systems have less than 10 - or not much more. Is this something to track down?
How can I tell if it is of any concern for the user of the PC?
