Devnet is failing to run with fork-network

[mikiw]

Describe the bug (observed vs expected behavior)

Devnet is failing to run with: cargo run -- --port 1025 --initial-balance 500000000000000000000 --seed 42 --accounts 3 --chain-id TESTNET --fork-network 'http://rpc.pathfinder.equilibrium.co/integration-sepolia/rpc/v0_7'

Not reproducible on testnet

• [x] This issue is only present on Devnet and cannot be reproduced on the alpha-sepolia testnet (check the box if true).

To Reproduce Steps to reproduce the behavior:

1. Run devnet with CLI args: cargo run -- --port 1025 --initial-balance 500000000000000000000 --seed 42 --accounts 3 --chain-id TESTNET --fork-network 'http://rpc.pathfinder.equilibrium.co/integration-sepolia/rpc/v0_7'
2. Get error:

Devnet version

• I am using Devnet version:
• [ ] This happens with a dockerized Devnet (check the box if true).
• This does not appear on the following Devnet version:

System specifications

maybe the problem is with tokio join added recently - checking

[FabijanC]

doesn't happen if in release mode (--release)

[mikiw]

right cargo run --release -- --fork-network http://rpc.pathfinder.equilibrium.co/integration-sepolia/rpc/v0_7 works ...

[FabijanC]

I deleted my recent comment which was wrong (perhaps I should have just edited). The error is present even before commit 3ad81456 (immediately before #491 was merged and tokio join introduced).

Could be a reqwest issue: https://github.com/mozilla/sccache/issues/1161 Here they mention the same release vs debug mode problem

Here's what chatgpt says about debug-release differences (link to chat):

The difference between debug and release modes can sometimes expose race conditions or timing issues in your code. Optimizations in release mode can inadvertently mask these issues. Running your code with more extensive logging or using a tool like tokio-console can help you understand the runtime behavior in both modes.
