I just checked my ipdevpoll.log and found exception listed bellow. It is a Cisco 3750 two members stack. This error was reported only two times today. I checked job statuses (all green) and ipdevpoll failure graphs and there are just a few of them. Is it normal?

It appears that the error occurs inside the pynetsnmp library, while processing a response from the device. Since it's in third party code, and seems to be only intermittent, I don't think there is much we can do about it.
Given that it happens only twice a day in the 1minstats job, it's not going to be much of a problem for you, though. You're not going to miss 2 out of 1440 daily data points for your 3750's CPU load average.
