[Swift-devel] stale nfs problem

[Glen Hocky]

Hey everyone,
this isn't quite a bug but more of a feature selection. I had some jobs that
I started with swiftwork on /gpfs/pads before they turned it off for
maintenance. The jobs in the queue were put on hold and then restarted after
pads was back. Jobs ran or were running, but when they started to finish, I
got the error

Perhaps in future versions it would be possible to catch this exception and
make one try at rectifying the situation
