If I remember from your original posting that you are doing sequential
rsh and eventually it starts giving time outs.

I saw something like this starting in FreeBSD 3.0 when we use rsh
to do sequential remote dumps (especially noticable on larger partitions).
It acted like FreeBSD stayed in CLOSING state too long. A sleep (I chose 
60 seconds because it worked) would let the previous rsh command to close
before starting the next one. Obviously, you do not want to do that. I
am just throwing this idea out to see if we can define the conditions
that cause your problem.

I don't have your original post, but I thought it was the one where      
netstat on each side had one side of the connection in a closing state
but the other side had already remove the connection.

It would be interesting to get the netstat of both sides when you are
using the FreeBSD <-> Solaris and FreeBSD <-> FreeBSD. Does this problem
existing in the FreeBSD <-> Solaris case when the role of FreeBSD and
Solaris are reversed?
