I am trying to create hundreds of host, application and items. It is same java application, which creates host, application and item using same JSON request and works for sometime then it doesn't create host, application and item. When I retry it, and it works fine then it fails after a while.
The ONLY thing is changing is the name of the host, application and item in JSON request.

Attached is the zabbix.log file. You can see that it creates for a while, and then it gets the create exception.
Thanks
