We are having problems with the traffic counters, some of them appear to be implemented as 16 bit counter instead of 32 bit counters. The reason this is causing problems is that they roll over (at 65,000) to 0 in less than our minute polling cycle, really skewing our metrics.
The counter for the Lan (interface 2) seems to be functioning properly, however interfaces 3 and 4 (WAN and DMZ / WAN2) rollover at 65000.
