After calling the infamous Sun Hotline 4 times without any response, I'm
posting a note here in hopes someone has seen this problem and know of a
solution:

The Problem:
------------

	Periodically, (about once a week on a 4/280, less often on
3/XXX) we experience the following panic:

[orchestra]panic: vn_rele
[orchestra]syncing file systems... panic: vn_rele

(the "[orchestra]" stuff is added by out console switcher...)

This *appears* to happen under the following circumstances:

	- One or more filesystems are automounted from a 3/XXX series
file server.
	- One or more users are getting their home directory via automount.
	- One or more users are somewhere else in the file tree then
their automounted home directory.

These events happen weekly on our source machine (orchestra) and less
often elsewhere.  I've seen this panic happen most often on 4/280's, but
also on 3/280s and our 3/180.  So far I've been busy fixing other things
to really dig into this.  If you have looked at it, I'd love to hear from
you!

Question time:
--------------

	* Has anyone else had this panic?

	* Is there a fix for it?  (I don't believe Sun has one as I
*have* been called back by the Hotline folks when they have a fix for
something)
