Howdy Nico!

Sorry it has taken us so long to respond to your request. We have been swamped 
in support these last few months.

I would first check to make sure that the netCDF you are using has been built 
for parallel access. That requires that the underlying HDF5 library be built 
with --enable-parallel, and that both HDF5 and netCDF are built with the same 
MPI compiler wrapper you are using for your parallel I/O program.

I would strongly suggest you try the latest beta release, or the daily 
snapshot. Much has changed with parallel I/O and these problems may disappear.

Please let me know if this doesn't work for you.

Thanks,

Ed
