[sc-dev] sendallto errno 47 Address family not supported by protocol family

[Joachim Goßmann <jo@xxxxxx>]

Hi,

sorry for cross posting - I suspect a bug in the OSC implementation of 
SC could be the reason for this:

I use SuperCollider on OS X in an OSC-loop with a JAVA application on 
another machine in a museum installation:
A WACOM-tablet is connected to SClang (OSX) and it's events are 
forwarded to the JAVA-app, which in turn instantiates, modulates and 
deallocates synths in an SCServer (OSX).

It runs great generally, only it occasionally (and unpredictably) 
posts..

> evtype 25

...into the post window.

Even more seldomly though, the SCServer becomes totally unresponsive to 
commands.
This happens about 2-3 times a day on a busy day, and the post window 
always reads somewhat like this:

other occasional messages include

OSC communication is quite heavy, with each WACOM-event triggering up 
to 200 parameter changes (synths are allocated much more rarely, mostly 
on button presses)

What could be the problem?
