As the one who raised the issue recently: we’re rolling out 6.11 for testing on a couple hundred machines right now. I’ve scheduled this internally to run 8-12 weeks due to the fleeting nature and will report back if it pops up again or after that time has elapsed.

AFAICT this is a fix in any case even if we should find more issues in my fleet later.

Cheers,
Christian
