You have a race condition where auditd gets a signal to shutdown and an event 
indicating that shutdown is occurring. On shutdown, the audit daemon does not 
alter the rules or whether auditing is enabled. (This was to get shutdown AVCs 
for selinux.) There is a chance that your event is in syslog's files.

The daemon end event should give you 2 things, who issued the shutdown (auid) 
and the sending pid. That should let you track it down.
