1138	Random psFitsOpen and fitsClose failures during ppImage via NFS	jester@…	Paul Price	"I just processed 1688 SDSS pixel files through register, chip and cam. 3 of them fail with errors when opening or closing the fits files. All 3 were read or written via NFS.

The error messages I got were:

The first error happened twice, the second one once (low-number statistics, but I've seen the second one before).

The files process fine if I restart them, i.e. it's nothing to do with the file as such - just random other things, and I'm guessing it's something to do with NFS since it only ever happens for jobs that run on hosts other than the one carrying the disks with data and work directory.

I sent an email about this before when I saw it in 2.6.1, but since it persists and there is no real reason for failure, I thought it would be useful for robustness' sake to track this down.
