I have tested it and it seems that the close_connection() is indeed called twice in this situation. I now mark the fd as closed by setting it to -1 and then I check on that. If it is -1, the function exits immediately.

PS2, Line 327: 	if (osmo_fd_is_registered(&conn->fd))

Done

PS2, Line 329: 	close(conn->fd.fd);
> the normal solution employed in various other examples is to set 'conn->fd.fd = -1" at every close. […]
Done
