do not write to nfs-mounted file system: it is a recipe for disaster

it looks like an error while writing to unit 5. Errors like this,
occurring in system library calls, are impossible to pinpoint
unless one finds under which exact circumstances it occurs,
whether it is reproducible or not, and so on and so forth.
They are more often a sign of problems with mpi or the
filesystem or both rather than in the code itself
