that comment was over 2 months ago, and even if it was relevant then, it’s likely not relevant now. @halfer you likely know this better than me: sprites is undergoing some changes on the storage layer.
i would say, the amount of snapshots is unlikely to be the problem, and i am inclined to bet this is going to be the cause of zombie sessions.
@cerebration try this: sprite console list — if you se more than what you expect, terminate the older ones, or all of them. then try getting a new console.
