  UGH this is a wrench in the works...
  I was hoping to grab all the rotated logs, process them while still allowing audit
to run with no interruptions. Problem I run into is I run ausearch -i > /tmp/file and then
do ausearch -i /nfs/file with auditd stopped, then compare files and if they are the same in
size then delete the /tmp/file. I do this to make sure I get the log in the nfs archive directory
and the /tmp is a backup if there is a problem. If audit is running there is no way the files will
be equal in size while processing the /var/log/audit data in two different intervals.

  Thanks for feedback on this Lenny.

David,

It won't work like that; exactly the issue I described:

[root slim root]# mkdir logs-test
[root slim root]# cd !$
cd logs-test
[root slim logs-test]# auditctl -m "TEST message"
[root slim logs-test]# service auditd rotate
Rotating logs:                                             [  OK  ]
[root slim logs-test]# cp /var/log/audit/audit.log.1 .
[root slim logs-test]# ausearch -i -f `pwd` -m USER
<no matches>
[root slim logs-test]# grep TEST audit.log.1
node=slim type=USER msg=audit(1250529052.265:305135): user pid=8191
uid=0 auid=500 ses=4172 subj=user_u:user_r:user_t:s0 msg='TEST message:
exe="/sbin/auditctl" (hostname=?, addr=?, terminal=pts/18 res=success)'


LCB.
