Named pipes are not the the current NFS protocol (v2), but they are
supported in some NFS implementations.  In SunOS 3.2 named pipes were added
and the corresponding NFSSRC 3.2(may be off on the number), which many
vendors base their NFS on, included a kludge to handle named pipes
correctly.  Most vendors have picked this up but not all.  

It would appear that either Encore is running an NFS based on an old
version of the reference port or they built their own from scratch.
In either case it is a problem with your vendor's code.
