turning off file locking

[Rajeev Thakur]

The problem isn't with pnetcdf. The problem is that you are accessing files
on an NFS file system, and the MPI-IO implementation that pnetcdf uses needs
file locking to work on NFS for consistency reasons. The error you are
seeing is usually because the NFS lockd daemon is not running on the
machines. Could you check that?
