Hi Arne,

Sorry to hear that.

That one is known as well as test_cancel_concurrent_3 and one in geosparql (which is rarer). It seems to be related to the load on the machine. It may indicate a problem but it is only the conistency tracking that is complaining. Oddly, I have only ever seen one of the tests fail at a time, not both.

It's happened to me on my desktop once in the last 6 months that I can recall and I've been doing a lot of whole-jena builds over the last few months with the clearfing up for Jena6.

It does happen on Jenkins and github actions. For GH actions, rerunning almost always then succeeds (uses the same build VM?)

Could we have another PMC vote on the release please?
