I've noticed one issue with NFS that may or may not be related. Some NFS systems are "clusters" of storage nodes that are striped across the set of machines. In these NFS systems, a client connects to one node, and the information may propagate to other nodes after some time lag.
If you're using condor, this means that your NFS mounts on the submitter and execution nodes may be out of sync...since each mount may be to a different physical storage cluster node.
Adding small delays after writing files that both the execution and submitter node need to see fixed the problem for us.
