Sounds like the dispatcher is not taking events fast enough.

This would kind of indicate that you are only using the hardwired events from 
SE Linux, pam, and a few other apps. You shouldn't really be getting much 
traffic.

1.0.16 has been stable for a very long time. You might see what kind of events 
you are getting. 

aureport --start this-week -e --summary -i  

Tracking down what events are suddenly showing up might help find the problem.
