Constant ReadTimeoutException logs

[dzervas]

I'm running minecraft server chart 4.23.2 with fabric and some mods.

I constantly see the following log lines:

[04:21:38] [Netty Epoll Server IO #3/ERROR]: Exception occurred in netty pipeline
io.netty.handler.timeout.ReadTimeoutException: null

I disabled the healthchecks from both the docker env (DISABLE_HEALTHCHECK = TRUE and by setting readinessProbe.command: ["true"] and livenessProbe)

I still get the same log lines every minute? every 2 minutes? Not sure

I can't find a way to debug it either. there's no exception stacktrace and even if there was I imagine I'd get a bunch of built-in java classes.

My guess is it is something external and/or a interaction with a misbehaving plugin. The liveness probe is defaulted to period of 5 seconds so that doesn't match the one minute interval you're seeing.
