Cannot get sar to log system stats s10u9.

I cannot get sar to accumlate system stats.  sar is enabled via svcadm, sys crontab has

 0 * * * 0-6 /usr/lib/sa/sa1
20,40 8-17 * * 1-5 /usr/lib/sa/sa1
5 18 * * 1-5 /usr/lib/sa/sa2 -s 8:00 -e 18:01 -i 1200 -A

Interactive sar works, but I just get

# sar

SunOS xxxxxxxxxxxx 5.10 Generic_144488-12 sun4v    05/13/2011

09:52:05    %usr    %sys    %wio   %idle
09:52:05        unix restarts

# ls -l sa13*
-rw-------   1 sys      sys        16864 May 13 09:52 sa13

sys is also enabled in cron.allow.

Any help would be appreciated.

I am famliar with infodoc 1012484.1 and svcadm blowing away the sys crontab, but I don't believe that applies here.
