Something like the following shell script will make the problem go away:

#!/bin/sh
killall cron
sleep 5
/etc/init.d/cron start

Set up that shell script in your root crontab entry to be run as often as
seems necessary.  In a well running system (including the network), that
should be no more than twice a month.  That is because the bug doesn't
cause problems until cron has been SIGHUP'ed at least twice, which happens
in the shipped /usr/spool/cron/crontabs/root on Sunday morning.
I have not tested this script, but something very similar has worked fine
for me on SVR3 on PC-AT clones, where cron lacks the ability to cycle the
log at SIGHUP.

Publishing software fixes is a surprising amount of work.  It's no sweat to
dump something in an anonymous FTP pool.  It's rather more to document
what, where, why, and how.  Then there is dealing with the flood of
complaints from those unable to make it work.  Postmaster@sgi.com gets a
steady stream of requests for help with things which suppposedly available
"without support" on sgi.com.  (If you hadn't thought of writing
postmaster@sgi.com for help, don't start now.  Most such requests are
discarded without acknowledgement.)

Then there are the many people who do not have access to the Internet.

Still, it's possible someone will decide to spend even less time with the
family, and prepare the README, compressed tar file, and so on.


As Dave wrote, if time on your system is leaping backwards or forwards
noticably, then something is wrong.  I'd check that the time master is not
completely bogus.  I'd also check that timetrim in
/usr/sysgen/master.d/kernel and /usr/tmp/.timetrim are not bogus.  If you
set the adjustments too far wrong, then the time daemon will to jerk time
around.

Timed and timeslave change the time smoothly without upsetting cron, even
when the clock is "ahead," unless the adjustment is outrageously large.

All 3 errors on 4D/25's with RE2's are caused by an error of mine which
turned on some error messages which should have been on only when building
debugging versions of the driver.

The errors themselves are not affect by either my mistake nor the fix.
They are and will continue to be counted in the relevant counters visible
with `netstat -i`.

That is a form of physical security, and *may* do the job for some
machines, in some environments.  That was why the locking bar was
designed into the Indigo.  Of course, the disks can still be removed
by breaking the plastic, in that case.  On other machines, you may
have disk drive cables external to the enclosure.  It isn't a simple
problem.   It usually comes down to locking the machine up in a 
secure room, if that level of security is important to you.

  Hey,
  I need help to install FDDI on a SGI 4D/340 S. We are running IRIX 3.3.2
  and FDDIXPRESS 1.0. The FDDI board is well installed on the VME-Bus and
  the software is also installed as described in the manual. After
  rebooting the machine we typed "smtstat", but it showed us MAC=OFF.
  Now my questions :

        1.) (The kernel is reconfigured, changes was made in /etc/ethers,
            /etc/config/netif.options ..) What I have done wrong ?

        2.) We want to use the machine as a single attachment station,
            how can I configure the machine ?

        3.) How can then I use FDDI with ftp etc. ?

        4.) How must I connect the transceiver (A and B cable) ?

        5.) Is it possible to use also a ULTRANET board at the same
            time ?


  If somebody could help or have experiences on it, please mail me at
  once, because we are really helpless.


  Thanks for your efforts,

Subject: keeping the sprite in a fixed position
Date: 13 Apr 92 14:26:37 GMT



	I have an application in which a large image is displayed within
a window.  The system uses a trackball not a mouse.  Using the trackball
the user can change the viewable portion of the image by grabbing some
point and dragging the image.  This only works until the sprite hits
the edge of the window, they user must once again grab and drag the image.

	What I would like to do is allow the user to lock the trackball
into the window displaying the image.  Then when the user moves the
trackball the portion of the image which is viewable changes according
to the trackball movement, but the sprite does not change position.

        The image is rendered onto a GlxMDraw widget.

	I am assuming (bad or not) that the X server moves the sprite
automatically and that I would have to warp it back to the position I 
want.

        while (1) {
            get the next event

            if (the sprite has moved ) {
                move the sprite back to the fixed point
                move the image inside of the window
	    }
            else {
                process event
            }

	I am still having problems with input focus under 4.0.
I removed the getbutton() calls from the code in the interest
of standardization, replacing them with fl_qread() and fl_qtest()
(Forms Library versions of qread() and qtest() ). My code now
works fine under 3.3.X (i.e, I can put the pointer over a window,
hold down the shift key, and move the pointer out of the window
w/out losing focus).  Under 4.0, it refuses to lock.  This makes
it impossible to stretch my rectangular rubber band across multiple
windows to define an area for scrsave.  How do I lock input focus?
If possible I'd like to do it in software so that the user
is unaware of it.

Well, that's sort of an understatement. *All* backup programs
(including the restore half of dump/restore) fail at maxpathlen; bru
fails at 127 characters. Among the other utilities which fail at
maxpathlen is fsck, on every UNIX I've tested. (I admit to not having
tested IRIX, as our IRIS doesn't have a filesystem I can afford to
fsck. But the bug is common to Sys V and Berkeley fsck.) Stop at
maxpathlen, or you're in for serious grief.

Actually the problem just occurs each time cron performs an internal
re-initialization - after a few of these, it overwrites part of its memory.
It has been there for a while, but now there are additional cases where
cron re-initializes:

1) when you send it a SIGHUP to get it to re-read the crontabs
2) whenever time goes backwards (this is new in 4.0 and is most often
	caused by an errant timed master/slave)
3) time goes forward by more than 7 seconds.

Most of these cases really only happen when there is something wrong with
network time maintenance. If time is going backwards, cron will print
that it discovered this in its log (/usr/lib/cron/log) - if you
see a bunch of these, then you will need to restart cron.
