I get Error: read ECONNRESET at TCP.onStreamRead after some running time

[nehemiekoffi]

Steps to reproduce

• Run loopback4 app using "loopback-connector-mysql": "7.0.13"
• All endpoints work fine
• After some time (e.g 2 hours), try to get data from an endpoint
• I receive error 500 Request GET /settings failed with status code 500. Error: read ECONNRESET at TCP.onStreamRead (node:internal/stream_base_commons:217:20)
• After 3 or 4 retry, then I get a good response from the server.

Current Behavior

• I get error 500 after some running time (e.g 2 hours) with my loopback4 app
• But I have a loopback3 (node 14) application connected to that same database that is using loopback-connector-mysql": "^5.4.3" and I do not have such error even after 24h on running

Expected Behavior

• I should get the response from the database without error

I can confirm, that we are investigating similar, maybe same, issue for a few months. Up to this date we were tweaking database to fix this problem but without success.

After some up time we are seeing this error in logs:

Request GET /v2/auction/31 failed with status code 500. Error: write ECONNRESET
