Given how the block production is driven for Parachains right now, with the enabling of async backing we would produce two blocks per slot. Until we have a proper collator implementation, the "hack" is to prevent the production of multiple blocks per slot. Closes: https://github.com/paritytech/polkadot-sdk/issues/3282

title: Parachains-Aura: Only produce once per slot

|
With the introduction of asynchronous backing the relay chain allows parachain to include blocks every 6 seconds.
|
|
The Cumulus Aura implementations, besides the lookahead collator, are building blocks when there is a free slot for
|
|
the parachain in the relay chain. Most parachains are still running with a 12s slot duration and not allowing
|
|
to build multiple blocks per slot. But, the block production logic will be triggered every 6s, resulting in error
|
|
logs like: "no space left for the block in the unincluded segment". This is solved by ensuring that we don't build
|
|
multiple blocks per slot.
