Looking for some advice/a hint

Hm.   Are you connecting over a TCP domain socket?   I assume so.
It's possible that downing the interface is blowing up the socket.
This wouldn't happen on BSD, but it's a perfectly valid thing to do
for a TCP connection, particularly if it's not to localhost.   OMAPI
really needs the ability to do local-domain connections as well.
Sigh.

Yeah, that makes sense.   That may be why you're losing, actually.
