Hi Zabbix team ,

I've found a possible issue while developing some scripts to dynamically create Templates/Items and Hosts .
The issue can be spotted while running the host.create API call simultaneously . I've not tested with other API calls like item.create or template.create but I suspect that it will be the same outcome .
The outcome of this run is that Zabbix will create 2 hosts with the same name . If I run the call's with some time difference between them , the 2nd call seems to return a error saying that this hostname was already created , which is fine , but I would expect this error coming up while I run the simultaneous calls also .
