Thanks to Andrew Rotramel, John Riddoch, Ted John, David Harrington,

Unfortunately, it seems there is no way to get this to work, short of either 
stopping all the processes that use some exports of server A, or of rebooting 
client B.

Note that Solaris 8 clients have not this problem.  For them it just works.

Here is some advice I received.

I can see the point, but on the other hand, /net is so convenient.  Also, 
Solaris 8 seems to get it right...

I asked:
