Random data point: I had these yesterday on a VPS-based relay.
My main question: How do circuit creation requests on one's Tor relay cause load on one's network infrastructure? Is it DNS requests? Is it TCP connection state entries? It's not bandwidth, we observed that above, and my router can handle far faster pipes than the one it's on currently. The DNS failing is a sign that the router is under severe stress.
Possibly your uplink is full (supposing you're on some DSL), and is starting to build up ping time; then DNS requests to the outside can start to timeout.

Over roughly the same time frame I received an incredibly high number of spam e-mails in one e-mail account that normally gets 20 or so a day on quiet days. Perhaps this is another example of mal-ware in action.
