[Samba] NT_STATUS_RPC_INTERFACE_NOT_FOUND / DCERPC_NCA_S_OP_RNG_ERROR

[Peter Eriksson]

Every time I restart our Samba file servers I get the following errors/messages in the log files. Everything seems to work just fine though, but it’s still annoying.
I’ve tried googling and I just find other people asking about similar errors but no real answer… 

Are the messages indications of errors or just debug/informational messages that can be ignored?

(Samba 4.13.4 joined with Microsoft AD 2018 servers)
