Strange snmpd messages

OMSA does use its own SNMP daemon, but the way it's configured is that
it sets itself up as a SMUX peer of the OS snmpd. This means that for
any requests under the OMSA OID the OS snmpd will forward to the OMSA
SNMP daemon. That is the connection that you are seeing.

Subject: Strange snmpd messages

Hi all,

In the last few days we've been seeing huge chunks of these every so
often 
in /var/log/messages:

Jul  2 10:59:54 niven snmpd[4610]: Connection from - 10.0.65.4
Jul  2 10:59:54 niven snmpd[4610]: transport socket = 12
Jul  2 10:59:54 niven snmpd[4610]: Connection from - 10.0.65.4
Jul  2 10:59:54 niven snmpd[4610]: transport socket = 12

(where niven is 10.0.65.4)

Does anyone know why these would be occuring and why we haven't noticed
them 
before?  I've tried uninstalling and reinstalling OMSA to ensure the
drivers 
are built for the right kernel but it hasn't stopped them.

I found this RH FAQ entry: http://kbase.redhat.com/faq/FAQ_40_10731.shtm
but 
it's odd as I thought OMSA included its own SNMP daemon rather than
using 
the OS-installed one.  Not only that but chkconfig has told me that snmp
is 
not being started at boot.  Therefore it appears that OMSA _is_ starting
the 
OS's version and not its own.  All a little bit strange.

Details: PowerEdge 2950, RHEL4 u5 x86_64 (2.6.9-55.0.2.ELsmp), OMSA
5.0.0

What other information would help?
