You mention that you moved it to an NFS volume - but it seems you also moved to
a grid configuration using PBS?
If that's the case, what you are seeing might be an issue with NFS attribute
caching or write caching, which causes files created from one machine to not
appear until some time later
Well, I didn't move it to a grid configuration using PBS recently, it was
already using a grid configuration with PBS before I moved it to the NFS
volume and no such an error ever happened :) So it must be related to NFS.
Thanks for you great suggestions! I will try them out and see how they
