That's funny, I posted the EXACT SAME PROBLEM here today:

http://groups.google.com/group/microsoft.public.dotnet.distributed_apps/browse_frm/thread/dc0437df318f79c2

The sleep solves it, but it's a kludge I'm not happy with.  I thought I
was getting duplicate data, but it might be as you said... missing data.

Druid,

Thanks, at least you have confirmed my suspicions.  I'm not willing to go as
far as say Sockets is bugged (I've been wrong too many times in the past). 
However, I do think there is some sort of option that needs to be set/altered
or some action that needs to be taken.

I've taken the time to alter my code to send entire byte arrays (dynamic)
instead of packets and the same problem cropped up, once the size got over a
certain limit.  Smaller arrays seem to work just fine. 

Thanks again for your help...
