socket hang up issues

[scorrea-ui]

Describe the bug

Currently, we are experiencing many socket hang issues coming from Unleash.

We are using Unleash Edge: v20.2.0 and the unleash-client npm package: v6.10.1

We run our toggles server-side using react-router v7.13.2

We also use the startUnleash function with the InMemStorageProvider, and followed your recommendations based on this article: https://docs.getunleash.io/guides/implement-feature-flags-in-aws-lambda

Any help would be greatly appreciated.

Steps to reproduce the bug

1. Use Unleash based on your lambda documentation and based on traffic you will most likely see these spikes come up and down

Expected behavior

That the socket hang-up issue is handled gracefully and does not spam our logs.

Logs, error output, etc.

This came from a GET request to /api/client/features, but we have also seen the issue on the metrics endpoint as well.

Hi @scorrea-ui it's unclear to me where those logs are coming from. Is it unleash-server, unleash-edge, or unleash-client (the SDK)? It seems you're saying they come from Unleash (the server), and that it's self-hosted, but you don't specify which version or docker image you're using. Would appreciate some more details
