Are your DA00 areas all on one machine?  AIPS encourages you to do
this but with Linux it is not a good idea.  Our $NET0 area contains
directory links to areas on the host machine.  Thus
    $NET0/PRIMATE
is actually a link to
    /home/primate/AIPS/DA00
which has the actual files.  The problem is that Linux does not handle
file locking well over NFS - files stay locked is the usual problem,
but I will bet this is connected.
