# CollateralDrainRatioOutOfBounds (/docs/errors/chain/CollateralDrainRatioOutOfBounds)

`sudo_set_collateral_drain_ratio` was given a value that is zero, negative, or above `MaxCollateralDrainRatio` (10). The drain ratio must be strictly positive — with no other exit path for miner collateral, a ratio of zero would make locked collateral permanently unrecoverable. Pass a `drain_ratio` in the range (0, 10].

Declared by the `AdminUtils` pallet; it classifies to the semantic code [`invalid_argument`](/docs/errors/invalid-argument).
