Scott, What version of mrtg are you running? I had an issue with failed polls producing spikes. I also suspected that a counter roll-over could have produced a similar result (but did not confirm). I have upgraded and the problem has been resolved. We are currently at 2.9.22 . Although not the same exact scenario, it may have relevance in your case also.
