Multiple harvesters conflicts

[adspx5]

ubunti 20.04 lts
chia 1.2.11

I prepared a machine and fully initialized chia. Created an image for boot over network.
After booting over network each harvester is getting chia init -c FOLDER
Start up service will be restarting service if harvester dies
Farmer is pooling to external pool... no usefull log information on farmer. all machines is in INFO.

Observation:
Either
farmer keeps the most recently connected harvester
or
all harvester dies with following message
or
in some cases it start working just fine...

Manual (without restart) chia init -c + start harvester -r - does not solve the problem.

Is it possible to run harvester loaded from same image?
What is proper way to initialized them?
Is it acceptable that farmer see harvesters from different ip under same id?
