We see the same problem w/NeXT 1.0.  The fault's in the BSDreaddir() code which
csh uses -- it does directory reads into a 512-byte buffer, which the NeXT NFS
server could probably handle but doesn't.  It's disappointing NeXT didn't fix
this in 2.0.  SGI's normal readdir(), used by sh, ls, etc. has a larger buffer
(4K?) and succeeds.  I'm told by a helpful SGI person that the next major
release will have a BSDreaddir() with larger buffer, but meanwhile we're stuck.

One thing you might try in the mean time: use tcsh instead of csh.
I think there are a handful of tcsh binaries up for anonymous FTP on
tesla.ee.cornell.edu and/or ftp.brl.mil.  We have "tcsh.iris4d-irix3.3.1";
it *does* successfully glob with the NeXT.
