1. Create new environment (CentOS, simple mode)
2. Add controller, compute, zabbix
3. Start deployment. It was successful
4. I successfully login to zabbix dashboard
5. But there is many errors in zabbix.log (node-21):

If you restart zabbix it dies (see screen)

And error appears in logs:

This is expected behavior, such record always appears when you restart zabbix_server. Also according to the logs from your snapshot zabbix_server was able to successfully start on node-21 after restart.

> If you restart zabbix it dies (see screen)

Restarted, dashboard and zabbix_server work fine.

> query failed: [2006] MySQL server has gone away

This might be cause by load spikes during deployment. After deployment is finished, zabbix_server worked for more than 2.5 hours on my env without a single alert in logs.

If you can reproduce it, please provide access to the live env with broken zabbix.
