for some reason, the stuck df and find processes are gone. 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,
