Many thanks to everyone who replied.  On Darren Dunham's suggestion, I
trussed
the running cron pid and found that it was having pam troubles.  After some
googling, I was able to come across some sunforum posts saying that
somewhere
along the line, Sun changed how PAM behaves in Sol 9.  I added these lines
to
pam.conf:

cron    account required        pam_projects.so.1
cron   account required /usr/lib/security/pam_unix.so.1

And restarted cron.  NOTE: You MUST restart cron.  I made the changes to
pam.conf and did not restart cron, and was still seeing it not working.

So after all this, it turned out to be not a SAR problem, not even really a
CRON problem, but a PAM problem :P

Many jeers to:

Thanks to everyone who has responded so far.  The suggestions have been good
sanity checks, but so far no one has figured out the problem.  Here is some
additional information.

- If I "su - sys" and manually run /usr/lib/sa/sa1, it works fine.  So it
appears to be a problem in cron.

- If I try adding a truss to the cronjob, I get no results back.  If I tell
truss to output to a file "/bin/truss -f -o /tmp/trace /usr/lib/sa/sa1" the
file never gets created.  Ditto without the -f.  Ditto if I don't use -o and
just use >>.

- I received many suggestions saying that cron wasn't running for a number
of
reasons.  /var/cron/log shows my jobs being executed.  The user can run cron
jobs.  I have tried changing the password in /etc/shadow to all manner of
things, no difference.

- Syslog shows nothing.  No mails are being generated, not to root, not to
sys.

- I received one suggestion saying there was a problem with openssh on sol9,
and that I should only change the sys crontab from the console.  I dragged
my
laptop over and plugged into the serial port.  No dice.

- I received a suggestion telling me about a problem with the Virtual SCSI
Device Driver on V240s.  I can't see that I am loading that.
# pkginfo |grep SCSI
system      SUNWfcp              Sun FCP SCSI Device Driver
system      SUNWfcpx             Sun FCP SCSI Device Driver (64-bit)
system      SUNWses              SCSI Enclosure Services Device Driver
system      SUNWsesx             SCSI Enclosure Services Device Driver
(64-bit)

If anyone has further suggestions, I am open to anything at this point.

Thanks!

Eric

Ok, I have a problem that is stumping myself and the other admin here.  We
just got some new servers in, a couple of V880s and some V240s.  We
installed
Solaris 9 on them (12/03 on the V240, 06/03 on the V880 when we saw problems
on the 240)  For some reason, sar is not working as it does everywhere else.
I am using the same crontab entries that I have working on a V120 running
Sol
9, and still no dice.  It starts up fine, but the incremental updates don't
seem to be happening.

Here are the relevant files and info:

# cat /var/spool/cron/crontabs/sys
#ident  "@(#)sys        1.5     92/07/14 SMI"   /* SVr4.0 1.2   */
#
# The sys crontab should be used to do performance collection. See cron
# and performance manual pages for details on startup.

There are no error messages in syslog or in my mail.

Any ideas?

TIA!  I will summarize.
