No problem.

That fails to surprise me.  I could describe issues to do with lots
of other Unices (if I could remember them!), IBM MVS and more.  File
access is traditionally perverse beyond belief, and Fortran's basic
I/O model and NFS are no exceptions.

Actually, from the traces you posted, one can argue whether gfortran
is using the optimal logic, but it's certainly doing nothing that isn't
reasonable in context.

Use ACTION='READ'.  If that doesn't work, then it probably IS a gfortran
problem :-)
