Bug Report

Setup

CometBFT version: tendermint v0.34.9 - cometbft v0.38.2

Have you tried the latest version: yes

ABCI app: Gaia, Evmos, Archway

What happened?

During the development of KSYNC, a tool to sync blocks stored on Arweave to any tendermint/cometbft based app chain, an error occured on the app every time the ABCI method InitChain was called over the socket protocol (error log below).

What did you expect to happen?

That the ABCI method InitChain can be called successfully called over the socket protocol by Tendermint/CometBFT without the app crashing.

How to reproduce it

It can be reproduced by trying to start the Gaia chain (Cosmos Hub) from genesis not in the default embedded in-process mode, but with tendermint running externally over the socket protocol.

  1. Install gaia with latest genesis version v4.2.1: https://github.com/cosmos/gaia/releases/tag/v4.2.1
  2. Init with ./gaiad init test --chain-id cosmoshub-4
  3. Install gaia genesis file
  4. Start gaia without embedded tendermint process: ./gaiad start --with-tendermint=false --transport=socket

(open new terminal)

  1. Install tendermint v0.34.9, which was used for gaia v4.2.1: https://github.com/tendermint/tendermint/releases/tag/v0.34.9
  2. Start tendermint: ./tendermint node --home ~/.gaia

Anything else we need to know

This error occurs not only for Gaia, but for every other chain where the genesis file is bigger than 100MB. And although right now this error only appears in chains which are still using Tendermint once the first chain based on CometBFT has a large genesis file this will result in the same error.
