NFS task x can’t get request slot

This one reared it’s ugly head yesterday, and has plagued me for some time. I have a farm of 9 computers that all use a single disk via a Network File System (NFS). During heavier use and testing I would start getting these errors from one of them, and then they would all go belly up, legs in the air, spewing out this error over and over. It makes a big investment look like a roach graveyard (or my livingroom, sometimes).

This time, however, I think I’m onto it. It always happens after a piece of our own software is run, and I think this software is writing files in an unorthodox way that NFS doesn’t handle well. If true, it’s the beginning of a solution, but there’s more work ahead.
