Initial response from support is that using CoreCycler is an 'unrealistic scenario' and they have to be able to reproduce it under 'normal circumstances'.Be interesting to see how you get on with this. It should pass at stock settings. Hopefully you update!
Frankly this ****** me off. Under 'normal circumstances' you might see only sporadic errors, so you use a stress test to isolate a cause and that's apparently 'unrealistic'. These are weasel words used to dodge responsibility.
