I have no idea what's actually happening inside the mempool, but something is very broken. In addition to the problem described above, I also observed internal mempool loops (transactions that are invalid being executed infinite times by checkTx), node disconnections (for bad behavior?) and weird stuff.

I have reverted the @melekes PR on 0.34.0 and everything seems to go to normal: https://github.com/vocdoni/tendermint/tree/revert_batch_txs
