Hi David,

Your ideas on how to fix this issue would be way more helpful than your NAK😉

Can you please explain why this fix is a problem? We have device X that sits on top of devices A, B, C, ... who are created and started before device X, to me it makes sense to stop device X first before stopping A, B, C, ...

Thanks,
Cristian
