What is sent there are 5 200 byte packets with random data to open up
NATs, so that we can actually receive back UDP packets for NATs that
have UDP "connection" tracking.

Unfortunately the server is not listening on that port, and we're using
the same socket for receiving UDP packets and sending these dummy
packets... so on the next time a packet is received, the socket reports
an error.

Please report this in Bugzilla? Thanks!
