SNMP 64-bit Octet counters rolling over quickly

[cburkins]

I'm using SNMP to query the counters on a RT-AC68U. There are 32-bit and 64-bit counters, but both the 32-bit and 64-bit counters seem to be rolling over rather quickly, several times per hour. Still doing some measurements to be sure, but curious if anyone has experienced something similar ?

Yup, the 64-bit counters seem to be rolling over at 4.29B, which I believe to be the maximum for an unsigned 32-bit integer. Weird.
