Kim,
Thanks for your reply. Lots of things there! I have merged my answers with
your questions below although haven't tried everything yet. Perhaps my
answers might give a few more clues to the problem though.

Yes, on some of them. 50% have this problem though.

Yes, tried this and /afs was still available.
