# LockIdOverFlow (/docs/errors/chain/LockIdOverFlow)

The global network-registration lock id counter reached its u32 maximum while queueing a subnet registration, so no new lock could be created. Check the `NetworkRegistrationLockId` storage value; this indicates lock id exhaustion, not a balance problem.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`limit_exceeded`](/docs/errors/limit-exceeded).

## Remediation [#remediation]

A chain-side capacity limit was hit; reduce the size or count of the request

The same explanation is available in the terminal: `btcli explain LockIdOverFlow`.
