A subsequent message of your verified that the hierarchy being read was on an NFS-mounted file system. Perchance, was that NFS mount managwed by amd(8)? If so, while I do not have a "fix" for you, I am relieved to see someone else finally report these symptoms. Please see <http://docs.FreeBSD.org/cgi/mid.cgi?20081203001538.GC96383>; for an archived copy of my initial message in a thread reporting this. There is additional detail (including kernel trace information & how-to-repeat instructions) in subsequent messages in the thread. Also mentioned is a circumvention -- basically, crippling amd(8) so it no longer attempts to unmount() a file system. However, I was unable to re-create the symptoms at home -- only at work. A colleague at work was able to re-create the symptoms, and was intending to experiment a bit more, but he's been busy with other things recently. Please contact me (off-list, if you prefer), and we can discuss additional details. Peace, david --=20 David H.
