[CentOS] snmpd log messages

I updated to CentOS 4.5 yesterday and now I am finding the snmpd daemon 
is logging reams and reams of these messages:

May 20 10:40:03 mx01 snmpd[2572]: Connection from - 127.0.0.1
May 20 10:40:03 mx01 snmpd[2572]: transport socket = 12

Is there a way to turn off this useless logging? I am getting these 
every 5 minutes (every time MRTG updates my MailScanner statistics).

So far what I tried was to take off the -a switch when starting snmpd. 
That didn't help. This snmpd behavior is new from CentOS 4.4.
