Increase SNMP Subsystem Priority in Sonicwall Devices

In the SNMP settings for Sonicwall devices, you can raise the priority for the SNMP subsystem so that when the CPU or RAM is overloaded on the device it will still report through the SNMP Agent. Under System->Administration->Advanced Management you can click the Configure button to the right of the Enable SNMP check-box then mark the setting "Increase SNMP subsystem priority"

Check the setting here

This is also documented by Sonicwall on their Knowledgebase:
