miniupnpd[13010]: sendto(udp_notify): Operation not permitted

According to my reading of the man page it is not possible to get this error
unless I'm using jails (which I'm not). The code in question does..

memset(&sockname, 0, sizeof(struct sockaddr_in));
sockname.sin_family = AF_INET;
sockname.sin_port = htons(PORT);
sockname.sin_addr.s_addr = inet_addr(UPNP_MCAST_ADDR);
while(known_service_types[i])
{
snprintf(bufr, sizeof(bufr),
"NOTIFY * HTTP/1.1\r\n"
"HOST:%s:%d\r\n"
...
n = sendto(s, bufr, strlen(bufr), 0,
(struct sockaddr *)&sockname, sizeof(struct sockaddr_in) );

(line 278 of miniupnpd.c).

Can someone shed light on what the problem is? The application appears to work
fine even with this error though.

man setsockopt, search for SO_BROADCAST.

Free time? There's no such thing. It just comes in varying prices...
