mobmuplat <> pd: port in use error #22

Closed batchku closed 7 years ago

batchku commented 7 years ago

I intermittently have this issue with the latest editor and pd 0.47.1 where i can't get the GUI (running in the editor, on my mac) to talk to PD. PD can send numbers to the GUI (running in the editor) but not the other way. I get this error when i open the PdWrapper patch:

bind: Address already in use (48)

connecting to port 54310
connecting to port 54321
bind: Address already in use (48)

I get this error even if i quit both pd and the mobmuplat editor; and then launch one after another.

Restarting the computer does the trick.

Somehow, somebody is holding on to a network port and not letting it go.

hmmm?

On a PC there is also no communication. I first launch "LaunchPureDataAndPdWrapperFromWindows.bat" and loading a patch has no connection. If I click on the connect object on PdWrapper it says 'already connected'. The trick/workaround is to close the patch and reload it. (leaving PdWrapper and the editor opened) Then, I click again to connect from PdWrapper ,and it works.

Yes, that means some other process is hanging on to that port (either a hung/crashed PD process, or something active that just happens to use the same port) You can find it and kill it, e.g. http://stackoverflow.com/questions/3855127/find-and-kill-process-locking-port-3000-on-mac
