I removed the getProtocolByName path by using a raw integer port number
and the error(s) still occurred. By listing /proc/$PID/fd I determined
that they were sockets (which are listed in a special format).

That investigation was prompted by strace(1)'s results, which indicated
that the error returned was -EMFILE from socket(2).
