[comp.dcom.lans] "Link has been severed" Problem *SOLUTION*

hallt@handel.CS.ColoState.Edu (Tim C. Hall) (03/20/91)

A hearty thanks goes out to all who responded to my posting asking
for help with a "Link has been severed" error.

In case anyone is curious...

PROBLEM:  Large files ( > 10MB ) transferred via RFS between hosts will
	  occasionally (about 25% of the time) terminate abnormally
	  with only a partial transfer and the above stated error 
	  message.

SOLUTION: This is apparently a BSD 4.2 bug that is fixed in the 3.2
	  version of TCP/IP for 3B2's.  Thanks to Muphy's Law, we have
	  3.0. It is some kind of problem with sequence numbers wrapping
	  around and tripping over the boundary.

A special thanks goes out to John Sims at US West for pointing this
out to me.  (I've been trying to mail you for days now)  Thank you
very much Mr. Sims, we will be getiing TCP/IP 3.2 very soon.
