OK, I have now installed a new version (2010.01.22) of the software
that should fix this problem.
Note to Rob Krakora and Alex Nemec: Please download and test this, to
see whether it works OK (and still avoids getting any "select()"
errors). I can't test it myself.
Important note: As a res
Ross:
No multicast packets are received with the 2010-01-15 version for which you
provided the fix. I looked at the TCP/IP stack source and it appears that
once a socket is bound it cannot be rebound. As a test I commented out the
'bind' code block in the setupDatagramSocket() function in the

My bad,

file for this kernel and the comment about it's needed implementation in *bold

I will debug this and let you know what is going on. Multicast data was

part to indicate to you that it was working prematurely. I will have

Well, beforehand you told me that it worked OK!
Anyway, the fix was to reimplement the "Socket::changePort()"
