[RPKI] Routinator and Bird becoming de-synchronized/protocol-error

I am not aware of any issues with RTR in Routinator 0.10.2 (which,
obviously doesn’t mean there aren’t any).

Can you perchance have a quick look what Bird says the reason is?
Either in Bird’s log (not sure if it logs anything related to that) or
in the PCAP -- the RTR error response has a human-readable reason
field. With a bit of luck, that might be enough to figure out what
the issue is.
