You may notice that the frequency drops when the bandwidth does. So it occurs every time a certain volume of traffic has passed. That suggests it is to do with 32-bit meters wrapping back to zero, and MRTG mis-interpreting the new reading being less than the previous reading. Possibly use 64-bit counters? Also I think a fair bit of work has been done to determine the difference between meter wrap, system reboot etc. Are you running a fairly recent copy of MRTG?
