Do you have a DDTS I can reference?
Not handy, but from cisco-nsp Archives I've found CSCea35259 and CSCdy30984, and a reference to CSCea63754 which I can't take a look at in BugToolkit. Symptom: SNMP output octet counter stops counting traffic (except some control plane traffic it seems), with every few days jumping by weird amounts producing such funny things like 150mbps spikes on a FE interface. I've seen a box with a nicely loaded FE (30-70mbps) which took (reproducably) just about 48 hours to have this interface stop counting. If this would have been a customer interface, it would have meant "reload router every two nights or lose money". This bug is supposed to be (finally) fixed in 12.0(25)S1. Given that you a) don't want to lose money and b) don't want to do two whole-network upgrades within a short time, going to 12.0(21)S7 to fix the vulnerabilty is no real option, so people are more or less forced to put their networks on bigger risk by going from 12.0(21)S* to (25)S1.
