And since df works again, I could see a nfs mount which I guessed caused the issue. Hm, so best guess, a hanging nfs mount is not good. I remember I mounted it without any special options. just "mount ip:/export /mnt" and probably forgot about it. I'll try and reproduce that tomorrow. I would say, a hanging nfs mount shouldn't lead to a hanging around df(1). all the best, Marian
