OrderBatchTooLarge
A chain-side capacity limit was hit; reduce the size or count of the request
The batch contains more than eight account-approved orders. Split execution into supported batches, retaining each signed order's original bytes and nonce. Classical orders retain the pallet's original total batch limit.
Declared by the LimitOrders pallet; it classifies to the semantic code limit_exceeded.
Declared at pallets/limit-orders/src/lib.rs#L548.
