I installed Zabbix 5.0.6 and tried to monitor VMware virtual machines.
I added some VMware hosts and apply a VMware template.
After several hours, I found query errors in zabbix_server.log
I tried the same procedure several times, but the the errors did not happen again.
There might be a race condition.
Steps to reproduce:
1. install Zabbix 5.0.6
2. add VMware hosts and apply a template for VMware monitoring
3. query errors sometimes occur
The messages written above are sometimes shown in zabbix_server.log
No error messages
