Problem

I started to see an error message on farmer logs. Maybe It is worth investigating.

This is an upstream issue, I’ll update yamux dependency and see if it helps in the next release.

Should be non-fatal though.

Can someone who sees this regularly test Snapshot build · subspace/subspace@e5a8236 · GitHub?
It has a change suggested upstream that may help with this.

According to @PuNkYsHuNgRy it helped, so Remove setting receive window size for Yamux by nazar-pc · Pull Request #2791 · subspace/subspace · GitHub will likely be included in the next release

Still haven’t seen it come up.

@nazar-pc Why not merge it to the main branch? I didn’t test it because it seems have no impact on the replotting.

It needs to be reviewed first, I’m generally not pushing code into main without second pair of eyes on it.

Testing is important because even small changes sometimes have unexpected consequences. I don’t expect any in this case, but it is also important to get confirmation from the community that it does actually help with the issue.
