## The Problem

If I stop the audioService component with the following command, it is successful, but the MangohRed consistently crashes after a few minutes. My ssh session is terminated, and I can see from the power monitor that the board goes through a reboot immediately.

> $ app stop audioService

Any Idea why this might happen?

I think I may have discovered the reason… It looks like disabling the audioService is not supported because the watchdog will restart the device?
