mkdir has stopped working - SCO Xenix

[mark baker 4206813]

One of my 386 machines running Xenix 2.3.2 has suddenly refused to let
any user, including root, from making a directory. The mkdir test command
generates  
        mkdir: cannot make directory test
I can create files ok.

Any clues please!
