I'm working on small zone zns, where there is many zone in device. it is corner case, but if there are too much metadata that Small zone cannot save all meta data at once, RollMetaZoneLocked loop occurs.

Hi!

Thanks for reporting this issue!

What zone size are you using? Are you using real hardware or an emulated device?

Best regards, Hans
