How much memory should it take?

[de-authority]

I don't think it's a bug. c2 will take more than 190GB. maybe 230+GB memory. see this:https://github.com/filecoin-project/community-china/blob/master/documents/resource/resource_usage/resource_usage.md

[Reiers]

Correct - I turned it into a discussion.
