@maan2003 We're we doing RWLock with a mix of reads and writes before? Maybe we should have some of the txes in that loop do only a read or skip...
@maan2003 I tried it locally and it hanged. And didn't seem to ever time out. Seemed weird, tried master and that finishes with success, so it does look different.
`nix flake build .#wasm32-unknown.ci.wasmTests` IIRC and `./scripts/tests/wasm-tests.sh` I wasn't aware that ... I have to open anything in the browser... ?

Oh, I see. I will investigate more tomorrow. Not sure if hanged or just wall of output or what exactly is going on.
I've played with it, tweaked this and that, and I'm unable to reproduce the hang. :shrug:

@m1sterc001guy I looked some more at it, and I think from our PoV, we should just customize rocksdb settings like in: https://github.com/romanz/electrs/issues/30
Nothing immediately to do it seems.
