SNMP not always working

Hello,

On a pair of CCR2216-1G-12XS-2XQ running 7.14.1, SNMP is not working all the time.

Whilst I can get a reply with snmpwalk, a query will often fails before doing a full walk, and when pulling data from LibreNMS or PRTG it will randomly fail to respond.

As such, we can’t calculate the traffic usage correctly on the interfaces.

Is this a known bug, is there a fix, or a workaround?

Thanks!
