[gnu.emacs.bug] Problem with wall and Gnu Emacs

roger%epistemi.edinburgh.ac.uk@NSFNET-RELAY.AC.UK (& Burroughes) (03/01/90)

	I recently mailed the sun-managers mailing list with a query about
emacs locking up when a broadcast message was issued, and had several replies
- one of which suggested that I get in touch with you, since the sender had
experienced similar problems and had fixed them with a patch from yourselves.

	Any help would be greatly appreciated - the original posting is
appended.

	Thanks.

<----------

	We have an interaction problem when running Gnu Emacs <VERSION 18.52>
on Sun 4/330s <SunOS4.0.3> and a broadcast message is issued using the "wall"
command.

	Normal usage of Gnu Emacs is fine, but the following problem occurs on
a reasonably consistent basis: each time a broadcast message from "shutdown"
(or directly from "wall") hits the screen, users who are inside Gnu see the
message appear - but then find that their terminals hang.  This happens on
terminals connected via SpiderPorts (and thus via Telnet) and on Macintoshes 
connected via NCSA Telnet across a Kinetics FastPath. It also happens if a
user is logged in from another UNIX host over the ethernet.

	No further action is possible for that user, although control returns
to the terminal if the Gnu Emacs process is killed.

	Since most of our users use Gnu a lot of the time, this is rather 
disastrous.  Anyone seen this or have any ideas as to what's happening?
