Uncaught ECONNRESET somewhere in our code base

[TimDaub]

Hi,

a node operator on Kiwi News always reports the following error:

We don't know where this is coming from, but we think it is libp2p. Before opening an issue, I asked in the libp2p TG if someone could help us find the cause of this, but it was suggested that I open an issue: https://t.me/c/2109810685/11/818

• Version: We use libp2p v0.40.0 https:/attestate/kiwistand/blob/41aa70347eb8786f1cefa6746aa700a563c053c1/package.json#L83 we don't really have budget to upgrade this ATM

• Platform: Ubuntu

• Subsystem: I'm not sure. But we use a variety of libp2p packages where this could originate from, see this part of the package.json: https:/attestate/kiwistand/blob/41aa70347eb8786f1cefa6746aa700a563c053c1/package.json#L47-L55

Severity: Critical because it makes our application panic

Description: This happens once two nodes are connected and exchanging messages. If one of the nodes unexpectedly crashes or gets terminated, then the other one will throw this error. I have checked most/all interactions I have with libp2p methods to make sure I'm try catching everything, but I haven't managed to find where this error is coming from. And also: the error doesn't have a stack trace, so I'm also unsure how I'd anyways find out more.

Steps to reproduce the error: Run two Kiwi News nodes, wait until they start the set reconciliation. Kill one node with Ctrl - C. Most likely the other will throw the ECONNRESET.
