[Tony Anecito <adanecito@xxxxxxxxx>]

Hi Wireshark group.

I narrowed down the redundant packets last night/this morning. I have notified the Sun group about the issue and am still looking at it closer.

Thanks for the help this has been a huge issue for me and now for Sun perhaps.

Best Regards,
-Tony
