Generally after you reboot your devices....you might see mrtg graphing a very higher value, because of counterwrap...
There are few alternatives you can use to overcome this issue.. 1) If you are sure that you link wont exceed any particular value say in your case (4 MB) you can use AbsMax[_]: 500000 that will make mrtg automatically ignore any value exceeding the 4 MBs and will graph a 0 instead. 2) You will have to manually delete the values from the log files (*.log) go through the log files and you will yourself know the value causing spike. delete those values and run mrtg. 3) There are few scripts as spikekiller (I am sorry but I dont have the link for it, my other fellow frens in here at the list might have..plz share) use those to cutoff the value exceeding.
