I upgraded Zabbix server from 4.0.4 to 4.0.7 and right after "service 
zabbix_server restart" zabbix starts to eat all CPU

I tried to restart Zabbix and reboot of the machine (VM in VirtualBox) 
but no change.

Are there somebody running Zabbix server 4.0.7 with IPMI pollers without 
this CPU issues?

The CPU was almost idle before upgrade.
