RHEL5 snmp errors

[Timothy]

I'm getting the following snmp errors:

snmpd[18707]: error on subcontainer 'ia_addr' insert (-1)
last message repeated 3 times
snmpd[18707]: error on subcontainer '' insert (-1)
last message repeated 3 times

I'm running rhel5 xen (kernel 2.6.18-8.1.3.el5xen) and snmp 5.3.1-14.0.1.el5.

When I googled I see other people have the same issue and that it's related to 
duplicate IPV6 addresses.  Is there a fix for this?
