After successfully paying out a few addresses in a payout loop, the sendtoaddress returns insufficient fund and getbalance returns 0. However, when a new block is mined, getbalance returns normal amount, and sendtoaddress continue to work.

Note: This doesn't not block the integration with Yiimp, but still breaks the payout loop over multiple blocks.

The reason is a lack of UTXO liquidity.

The mass payout loop iterates through the receiving addresses and sequentially creates a single transaction for each receiver. This requires the wallet to have a sufficient number of UTXOs. Few large UTXOs won't help since each of them can be spent once, and the changes back to the wallet will have to wait until they are confirmed.

The number of UTXOs increases as every new block is mined for the wallet address of mining pools.

The wallet can also create raw transactions, or use something like sendmany to manually do the payout, or artificially break down large UTXOs into many smaller UTXOs to increase liquidity.
