Mike,
Intriguing. If I were you , I would
- Call Sun and ask them "why"
-Sniff the link with a telnet running cisco-cisco followed by sniffing between
Sun-Cisco
-study the packets
-Look for the problem other than these 2 routers .Likey .
-Test the Sun ports.
-Isolate problem on sun/cisco/other device/monitoring station and take off from there.

Subject: Re: Telnet session question - very perplexed on this one
I used to work on the TAC and remember a problem like
this. It was something with the Sun box. I don't know
why it only happens on that one router, but if I
remember correctly, that TAC case had the same
problem. If I didn't know about that case, then I
would say it would be the link between the Sun and the
Cisco. I don't remember the exact case so you might
want to open a TAC case.
Good luck!
