SuSE Linux: Version 5.2, 6.0
shutdown -h now
)
the following error message appears :
wall: /dev/ttyXXX: I/O error
wall
writes to all ttys (terminals), that are listed in the file utmp
.
However old versions of xterm
don't remove their entries from this file.
As a consequence, during shutdown, wall
tries to write to a tty, that is no longer in
use, resulting in the above message.
Also every terminal, that wasn't erased from utmp
by some other program, will cause
the same error message.
Get an update for xterm
. New versions of this program sign off completely.
A new version is available in the package xf86
under the URL
ftp://ftp.suse.com/pub/suse_update/S.u.S.E.-5.2/x1/xf86.rpm
If another program caused this error message, you should also get an update for it.
Please note, that this error message is uncritical, so it can also be ignored (not nice !) .
There is a mistake in kvt, the KDE terminal emulation.
Be sure to exit completely off of each terminal, before shutting down the system, pay particular attention to closing down pty's before exiting the X session.
There is a Bug (better yet: presently unimplemented code) in kvt. When kvt is ended by closing the window, neither the pty nor the utmp are deleted. It is unfortunately not at all easy to imp[lement this feature after the fact, and therefore there is still no patch available onour web site.
Solution: Close all kvt's before logging out.
Home users: Here it is OK, because there is only one user on the computer, to ignore teh warning.
If the computer still fails during shutdown, read the following article: http://www.suse.de/Support/sdb_e/bk_shutdownfails.html
