Background Network Junk Thanks Little Snitch
One disadvantage of running Little Snitch: You finally know all the background activities going on constantly and consuming bandwidth, memory and cpu cycles without your implicit acknowledgement.
I was not running any FileMaker products at the time. Apparently "helpd" wants to talk to their help server anyway.
If you run Little Snitch, you will have a great appreciation for how active an "idle" machine really is.
