[mrtg] Using Aggregate sometimes returns HUGE (incorrect) results

[Scott Freemire]

I am polling two Cisco 3825 Voice Gateways for current calls in progress.
Both individual graphs work fine (Target[172.24.100.4_1007]:
.1.3.6.1.4.1.9.10.19.1.1.4.0&.1.3.6.1.4.1.9.10.19.1.1.4.0:community at 172.24.100.4)
returning values anywhere from 0 to ~100.

My Aggregate graph (Target[AllCalls_1009]:
.1.3.6.1.4.1.9.10.19.1.1.4.0&.1.3.6.1.4.1.9.10.19.1.1.4.0:community at 172.24.100.4
+
.1.3.6.1.4.1.9.10.19.1.1.4.0&.1.3.6.1.4.1.9.10.19.1.1.4.0:community at 172.24.100.5)
usually returns the correct value - but several times a night it returns
values that show up as 40Gig on the graph! Sometimes the values repeat for
several 5 minute polls or even several hours.

I've played with AbsMax and MaxBytes, I've moved it to the top of the config
so there was a gap between it and the individual graph polls (at least in
the config), I've upgraded to the latest Perl and MRTG versions (which
actually made it worse).
Here's where I'm at now:
AbsMax[AllCalls_1009]: 300
MaxBytes[AllCalls_1009]: 75
Options[AllCalls_1009]: gauge, nopercent, growright, unknaszero
Unscaled[AllCalls_1009]: dwmy
WithPeak[AllCalls_1009]: ymw

Any suggestions?

Thanks,
Scott
