I keep restarting a device with OTAA, which triggers join. For every join accept I see new row in ns db, after first successful uplink it is also inserted into as db. Both of those tables seem to keep old data. Is it by design? Should users clean up those manually? I am running latest docker images.
This is by design as the network-server needs to keep track of the used nonces so that it is able to reject replay-attacks.
