Steps to reproduce:

1. Do nothing

Result:
Trigger "Proxy [pg1-1]: Zabbix proxy never seen" fired today at 01:11:39 CEST for no obvious reason.

It was only this one proxy. Other proxy in same group, and no proxy in other groups reported this.

Nothing relevant in server log, excluding "sending configuration data to proxy" it is:

769:20240829:005007.301 item "xxx" became not supported: Cannot evaluate function: item "xxx" is not supported at "last(//hrStorageUsed[di]) * last(//hrStorageAllocationUnits[/disk4])".
765:20240829:014833.292 executing housekeeper

Nothing in proxy log, excluding "received configuration data from server" and unreliable SNMP devices randomly not responding ("first network error, wait for 15 seconds" and "resuming SNMP agent checks")

Nobody touched server or proxy VMs since 7.0.3 upgrade - about 5.5 days ago.

Latest record in audit log is from 2024-08-28 02:51:21, adding temporarily discovered "/disk4", that will be lost again at 20240829:005007.

I see this is not enough to reproduce, but I still hope it can help.
