Zabbix + docker "problem more than 75%" how to fix?

Question

Zabbix

I am building docker zabbix using docker-compose from official. zabbix turnips. I set up telegram as a channel for sending alerts, now I constantly (every hour) get the error "Problem: Zabbix discoverer processes more than 75% busy" found that I need to edit etc/zabbix/zabbix_server.conf but I don't have this file found on the forums that in docker case you need to edit .env_srv
ZBX_VALUECACHESIZE=256M (just in case)
ZBX_CACHESIZE=256M
ZBX_STARTDISCOVERERS=5
did a reboot
Didn't help. Please tell me.
ps also noticed that docker ps now began to issue the name of images _1 before it seemed to be without a unit

Answer 1

It is easier to disable discovery after starting Zabbix in the configuration-discovery-disable control panel of everything that is visible. Most likely, the problem is that local subnet discovery, which is there by default, is trying to scan not the local subnet of the host, which is usually /24, but the internal (and empty!) subnet of the docker container, which is /20 or wider by default. .
