SNMP Error with haproxy.pl

[Kyle Brandt]

When I restart SNMP with:

disablePerl false
perl do '/etc/snmp/haproxy.pl';

SNMP fails to start with:

netsnmp_assert !"registration != duplicate" failed agent_registry.c:536
netsnmp_subtree_load()

Anyone run into this issue or now what that means? This is on Ubuntu Server
10.04

Thank you,
Kyle
