I can't tell you how many times I've had to debug a stuck process and it turns out that the logs indicated the NFS had a hiccup a day or two ago during a file read or write and the process was never notified of a file error. It's f!@#ing frustrating. Worse, though, was CIFS.

I routinely have to run file system scans on a giant NFS filer, and even without a hiccup, out of a 100M stat or read calls, ten or so will just never finish. In Go, I have to wrap the call with a channel thing and a time out and hope I don’t run out of threads before scanning all 400 M files.
