I have gone into the modules, selected tcpdump, specified br-ln with no other options and click scan. After about 3 to 4 minutes, I can change screens and that error will popup. This happens on all most all of the modules that I have installed (there aren't very many). There is zero logging that I am aware of for me to even look at to explain if the device is out of resources, or a bug. What is even more interesting is that the more you use the device socket errors, module unavailable errors popup.
