%IP_SNMP-3-SOCKET: can't open UDP socket
The SNMP server was unable to open a port for receiving or transmitting SNMP requests. This error usually occurs when the SNMP server is started using the snmp-server community configuration command on a router or communication server with an interface that has no IP address configured. Another possible cause is low memory.
Recommended Action: Configure at least one interface with an IP address or specify the no snmp-server command to remove the SNMP server process. Contact your Cisco technical support representative if problems persist or if it becomes necessary to add memory.
This might also fix your NTP problem as I'm suspecting that your interface may not have an IP Address.
