Pod Self-Test Error

Gang, Anybody seen this or is it just my luck: Lately (in the last 6 to 12 months), I have come across a lot of pods which fail their self test with an error '00' code. The pods all seem to work fine when used in an actual UUT, but whine when tested. I've seen this on multiple pods and multiple 9010s. Not really sure what an error 00 is, either. Since it's not service affecting, I haven't bothered to dig into it, but thought I'd ask before possibly wasting time on an issue someone else has already wasted time on. Anyone seen this? -Mark
