The SNMP communities on the device have changed and have not been updated in Ubersmith's Device Manager. The device is no longer responding to SNMP requests in a timely manner due to its CPU being overloaded. The appliance can no longer reach the device over the network. The device is down. Troubleshooting these conditions will likely correct the situation and reenable polling of your device.
