stopping "chatter"

I need to configure auditing for certification reasons, but I'd like to cut down on wasted disk space by ignoring known "chatter". On a newly installed Redhat 5 workstation there seems to be an open of /var/run/utmp every 10 seconds, which fills the log files. I'd like to ignore these, but my first attempt doesn't seem to work. I'm admittedly a novice at configuring auditd.

[root@foo ~]# aureport -f --summary | head -10

File Summary Report

5283 /etc/symc-defutils.conf

795  /home/fsotest/.gconf/apps/puplet/
662  /usr/include/linux/
599  /dev/null

[root@foo ~]# auditctl -l | grep utmp [root@foo ~]# auditctl -a exit,never -w /var/run/utmp [root@foo ~]# auditctl -l | grep utmp
LIST_RULES: exit,always watch=/var/run/utmp perm=rwxa [root@foo ~]#

What would be the proper syntax to get auditctl to ignore the open attempts to /var/run/utmp?

The audit system would not normally record access to that file unless it was told to. Do you see a rule that is watching that file? If so, comment it out or modify the rule so that it only watches for more unusual accesses like accessing it when there's a permission denied something like:

auditctl -a exit,always -F exit=-13 -F perm=wra -F path=/var/run/utmp
