Digging deeper, I've seen these messages pop up from time to time over the last 30 days or so, but not consistently, and I've never noticed the cpu pegged (but it could have happened, I don't use the machine that often).

In most cases, Tor spits out this message when it hits the CPU (core) limit. You might want to use munin or something similar to track CPU/memory usage over time.

Depending on the actual VPS limits, 250kb/s and/or 500kb/s burst might be too much for the slice. There's not much you can do about it then (as far as I know). If the VPS is OpenVZ based, check /proc/user_beancounters.
