I have experience a similar problem to this, though it usually seems
that there is a particular file in the directory which causes the
hang. In some cases, I've been able to suspend the process and do a
kill -9 to cause it to eventually die; in other cases that didn't seem
to work.
I usually see a message logged on the console and /usr/adm/messages when
this happens:
afs_vno_flush: m->busy
which is usually a sign of bad times ahead for some process.
I've also noticed problems copying large files into an AFS volume; it
may be a manifestation of the problem above since I've seen the
"afs_vno_flush: m->busy" message pop trying to do the copy, or it
might be unrelated. Its difficult to determine cause and effect..
I'm curious if anyone else using NeXT platforms as AFS clients have
encountered this hanging problem as well. I've told the folks at
Transarc about the problem, and they seem to be working on it, but I
have no solution yet.
