The above would imply a lot of logging activity.  It could either be the 
direct cause due to frantic logging, or some system event that would be 
inducing a lot of logs.

Are any of your logs "exceptionally" large in comparison to previous log 
files?

tail /var/log/daemon.log
tail /var/log/auth.log
tail /var/log/messages
