Thanks to;

Pavic, Aleksander
And anybody I may have missed.
I have not been able to resolve why this happens. Some of you have
suggested that this is just the way things are. Others have suggested
various things to try/investigate. Mr. Pavic suggested that there may be
some kind of problems with the DF (don't frag) bit on Solaris TCP/IP
packets. I have been unable to come to such a conclusion though.
I very much appreciate everybody's time and efforts. I will see if Sun
will attempt to help with this and if so, I will post the resolution to
this list.
Once again, thanks!
