Periodic error from Netty Epoll Acceptor IO Thread

[Bobrokus]

Describe the problem

I'm getting the same error periodically on Prominence II modpack server:

[Netty Epoll Acceptor IO Thread/ERROR]: Exception occurred in netty pipeline
io.netty.channel.unix.Errors$NativeIoException: recvAddress(..) failed: Connection reset by peer

Based on a response to other user's Reddit post the error is possibly caused by mc-monitor:

Apparently this is “itzg/mc-monitor” from the same developer, which is built into the image to monitor the server status. For some reason it doesn't work properly with the "Prominence" modpack.

A quick and temporary solution looks like this:

docker exec -it mc-prominence-container rm /usr/local/bin/mc-monitor

After this the error will disappear. In a good way, you need to understand how to disable this check on a permanent basis, because after updating the image the problem will return.

UPD. For a server based on itzg/docker-minecraft-server, just add the environment variable DISABLE_HEALTHCHECK: true.

I am going to convert to a discussion since I assume you were raising the Reddit post for awareness?
