My wild guess would be that doing deploy to the same machine breaks things badly, but I'm not sure if that's the case really.

Sounds like a big in nix copy

Seems like this issue is thrown by readInt from src/libutil/serialise.hh (readInt -> readNum). Something is clearly too big for copying, and size value seems to overflow. Now which one from all of these calls in Nix codebase...

Doesn't seem to appear anymore.
