> F0222 11:30:16.552686 23428 consensus_queue.cc:370] Check failed: request->ByteSize() <= FLAGS_consensus_max_batch_size_bytes (3042252 vs. 1048576)

> {code}
> It seems plausible that we might allow a write that is bigger than the max consensus batch size, and since there is a path in log cache that always sends at least one message, we might fail this check and crash.
> The workaround is to set a bigger value than the default for --consensus_max_batch_size_bytes
