slp on dual stack linux box

Hello LiveTribe Team,

  When I run a service agent and a user agent on a dual stack linux box using an IPv6 multicast address,  the service discovery does not work.  But when I run the same code bound to an IPv4 multicast address, it all works like a charm.  The unfortunate thing is that we need slp discovery to run on IPv6.  I've attached the log file of my IPv6 run.  What could be the reason for slp to not run on IPv6?  Below are some system/application config that may help you in your analysis:

 - slp version = livetribe-slp-2.0.1
 - java version = "1.6.0_07"
 - uname -a = Linux ctaf5 2.6.24-19-server #1 SMP Wed Aug 20 18:43:06 UTC 2008 x86_64 GNU/Linux
