[list.info-appletalk] aufs in D state

Has anyone seen this before?

I have KStar, version 7.0, running in a KFP-4, being administered from atalkad
version 1.2 on a SUN 3/280S, SUNOS 4.0.1. I use this to launch aufs sessions
(CAP version 5.0). Everything's fine for a while until an aufs session fails
to exit properly, ie a forked aufs process, instead of exiting, shows up as
an unkillable entry (in disk wait), in the process table.  Once one of these
rogues appears, subsequent new "aufs"es will go in to the same state,
hanging the Mac on attempts to copy data. The bad session SEEMS to be the
result of an unclean powerdown of a mac, but I can't be sure as the problem
is not reproducible.  I have not been able to make this happen using a
SUN IV / 4.0.3.

Your insight would be appreciated; I'll post what I learn.
