Steps to reproduce:
- install Zabbix Server and 45+ proxies
- use Proxies to monitor something, for example using simple checks with lot's of dependent items
- preprocessing manager consumes memory and also performs some processing, in log of the Server we can find information for items/dependent items which are not processed by Server itself:
If items are not processed by Server it's not necessary to shadow information on Server, since can use lot's of memory on a busy setup and also this can create additional locking.
