Miracles never happen.

Meaning that another instance of usbmuxd is operating with the process id 798.

Most likely this process was executed by something else on your system bypassing runit (scripts, your desktop environment, "magic utils" and so on).

I would suggest to see where this process comes from (you are lucky if PID 798 has a "tree" of superseding processes) and eliminate it.

ps, htop, and other process monitoring tools may help you to find this PID.
