Can you check the stackwise connection for bent pins? this is usually the cause for a damaged cable.

you can try replacing it with a new stack cable and check whether the error disappears or not

Make sure the cables are tightened all the way down , they can look like they are tight but are not . tighted to finger tight or use a screw driver but do not over tighten just till snug .This is not my favorite platform . You try to upgrade them them and they don't upgrade correctly even when you follow cisco instructions to the T , spent an hour the other nite upgrading a stack because i kept getting version mismatch and it wouldn't boot correctly even with the boot system switch all boot parameter.
