I just opened activity monitor to check something else out, and there seems to be something titles "radar_sweep" running rather erratically, making my data-written graph look like a wild earthquake is in progress. Basically the graph of data written shows 0 for one second, then about 794kb for the next, then 0kb, then 794, etc. I'm not sure it's radar_sweep, but that keeps appearing and disappearing on my application list. I'll post a screenshot, but having trouble uploading... I tried searching here and google for "radar_sweep" with no luck. Any ideas?
