We have six vaxstations running Ultrix 3.0 with the users'
filesystems from each machine crossmounted on all other machines.
Recently, we moved one machine to a different subnet and now
get the following message when mounting filesystems from the other
machines (on the other subnet):

Warning: cannot bind to privileged port: Can't assign requested address

However, the mount works and the data transfers are fine.
The message is symmetric:  Each machine gets the warning when 
mounting a filesystem from a machine on the other subnet.

Is this a known bug in Ultrix NFS or is it something I am doing wrong?

I have the following /etc/fstab entries:

/@epb1:/epb1:rw:0:0:nfs:rsize=1024,wsize=1024,bg,soft,retry=1:
/users@epb1:/epb1/users:rw:0:0:nfs:rsize=1024,wsize=1024,bg,soft,retry=1:
/@epb3:/epb3:rw:0:0:nfs:bg,soft,retry=1:
/users@epb3:/epb3/users:rw:0:0:nfs:bg,soft,retry=1:
etc...

We had to reduce the buffer size when going across the subnets because
of some inherent deficiencies in the Vaxstations (II and 2000) in handling
back-to-back packets that happen when the router is busy and bunches
packets together.
But, even before changing the buffer sizes we were getting the warnings.

Any help/pointers are greatly appreciated.
