NFS Problems

All of my NFS problems have just gone away. We've recently updated our Kernels to the latest RHES available. Looks like there was something hidden in there that fixed it for us. Wonderful.

I do realize that it's normal to see delay. Both due to attribute cache semantics and mtime granularity of one second. The problem I had here was quite different in that the dentry caches *never* expired negative entries.
