Rotating Gear with lots of Arp/Ping processes on Menu Bar on Mac

When I run IP scanner now on my mac, a rotating gear shows up on my menu bar (I googled, appears to be Automator related) and has like 10-20 Arp/Ping processes hanging off of it when i click on it. If I close ip scanner, it doesn't go away and I can't kill it. I have to reboot to get it to go away. What's wrong here, and how can I kill it without a reboot? It is definitely being started when I run ip Scanner . . .

As you have noted, the cog in the menubar is a new feature of Yosemite that alerts you when certain network tools are used. It does not seem to be something one can currently turn off. Since it is not part of IP Scanner it is also not something we can influence.

Here's what we think is happening: any time a network tool like arp or ping is used the cog now pops up. Since IP Scanner uses a lot of network processes, that cog shows up a lot. However, the cog should disappear when the process it is monitoring ends, and certainly when the app quits. However, it appears that the monitoring process that initiates the cog is perhaps itself buggy because it should not be possible for threads initiated from an app to keep running outside of the scope of that app - those should all get killed by the kernel when the app exits.

We are continuing to monitor the situation, and have released version 3.28 of IP Scanner, which imposes some limitations on how long threads can live to hopefully limit the time the cog displays when ping or arp or another network function is stuck:
