Re: Cannot join MulticastSocket

We have a client/server application that uses broadcasts.
While everything works fine under Win and Linux, the software
fails to join a broadcast group under MacOsX (Java 1.4.1)
with the message "No buffer space available".

Do I need to set or reserve buffer space before joining a group?
Do I have to enable some environment settings before starting the application?
Maybe a bad broadcast address? (230.0.0.1:8888)

This bug has been reported before, but we've had a hard time reproducing it. Our best guess is that it fails when a PPP connection is involved. We'd appreciate it if you would file a bug report and include the output of `ifconfig -a` at the time of the failure.

A possible workaround is to disable Java's IPv6 support:
java -Djava.net.preferIPv4Stack=true ...
