Try this from the Terminal:
killall -KILL pd
in my experience this does not help with hung [netreceive] objects. even more, i sometimes do have no pd-process any more anyhow (because it was quitted) and still the port is blocked and therefore not [netreceive] can be created.
it would be interesting to know which process actually locks the port ("lsof -i" usually does not reveal anything in these cases). if nothing else helps, a reboot will do (rebooting might be faster than waiting a couple of minutes)
i don't know of any (pd-side) solution to this problem, that won't make things worse. one (probably not so good) idea would be to actually create the object and try to get the port in a background process. however, this will make things very hard to debug.
