Comment 1 for bug 1646385

@Nick Moffitt,

Could you please provide more information?
Reproducible scenario will go a long way too \o/

Were you running any commands before add-unit? If yes, what were they?
Does waiting and trying again help? If yes, for how long do you usually wait to try again?
Does it happen all the time? i.e. you run add-unit first time and it fails, you wait and run it again and it succeeds consistently?
