Also struggling with this on my Raspberry Pi 4 running Raspbian. Also tried #535.

@jerbzz @lucianenache

modify your /etc/nsswitch.conf hosts: parameter
Change hosts: files mymachines dns myhostname
to just hosts: files dns

That should fix it, at least that fixed it for me when I ran into the issue again standing up some new arm hosts and disabling systemd resolve wasn't helping.

example my full hosts nsswitch.conf file looks like this:

# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

passwd:         files
group:          files
shadow:         files
gshadow:        files

#hosts:          files mymachines dns myhostname
hosts:          files  dns
networks:       files

protocols:      db files
services:       db files
ethers:         db files
rpc:            db files

netgroup:       nis```

Hmm, thanks for the tip @spencecopper. That's not quite what I had in nsswitch.conf. My hosts line was

hosts: files mdns4_minimal [NOTFOUND=return] dns

I made the suggested change, rebooted, and I'm still getting this (or similar) over and over about once a second:

time="2021-10-29T20:08:25+01:00" level=warning msg="update line fail, try the next one" error="Post \"http://chia-0df3c2fd4e.hpool.xin/proxy/wslines/chiaog\": dial tcp: lookup chia-0df3c2fd4e.hpool.xin: device or resource busy" file=loggers.go func=logging.CPrint line=162 tid=1

for my situation, I'm using a 64bit system, using hpool-chia-miner-linux-arm will have this issue.
hpool-miner-chia-linux-aarch64 works just fine

hpool-miner-chia-pp log (x-proxy-pp-linux 0 client connections)

jun 16 02:06:55 user bash[8872]: time="2023-06-16 02:06 55" level=warning msg="update line fail, try the next one" error="Post "http://192.168.0.1:9190/wslines\": dial tcp 192.168.0.1:9190: connect: connection refused"

How to fix it?
