RE: Failing to get config composition data

Hi,
It's not recommended to use the nRF52 to work as the provisioner for larger network especially for maintaining the database of the network.
It's suggested to use PC or mobile device for the task (we provide the PyACI interactive python for provisioning from PC)

For a large network in a dense area, you may consider reduce number of relay nodes. There is no point to have all 50 nodes with relay function when they are all in the same range. It may congest the network. Please try to reduce the number of relay nodes down to 2-4 in an area to see if the issue with SAR retry going away.

It seems this was to do with REPLAY_CACHE_ENTRIES being set too low. If I increase this value I notice that I am getting a lot more SAR NRF_MESH_SAR_CANCEL_REASON_RETRY_OVER occurring which slows down the whole configuration process.
