# CommitQueueFull (/docs/errors/chain/CommitQueueFull)

The subnet's Null timelock queue has reached its shared per-epoch limit of 64 KiB or 64 commits across emission mechanisms. Wait for the next epoch before submitting another commit; the leading eligible validator can preempt lower-priority rows.

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

Declared at [`pallets/subtensor/src/macros/errors.rs#L416`](/code/pallets/subtensor/src/macros/errors.rs#L416).

## Remediation [#remediation]

The Null subnet's shared timelock queue reached its byte or count limit; wait for the next epoch or for queued commits to reveal

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