We are experiencing an issue with SNMP item polling intervals when using Zabbix Proxy.

Steps to reproduce:

1. Set up a clean Zabbix Proxy instance (tested on both 7.2.X and 7.0.13 LTS/Zabbix Cloud).

1. Create a host with SNMP items and set the item interval to 1m.

1. Restart the Zabbix Proxy.

Observed behavior:

• Immediately after the proxy restart, SNMP data is successfully collected from the host.

• After that, item polling becomes extremely infrequent — at best, once per hour, sometimes even less frequently.

Additional information:

• We've tested this behavior on clean environments with only 1–3 hosts configured.

• Debug-level proxy logs have been enabled. From the logs, it appears as if the proxy is using its own (incorrect) polling interval.

• This issue occurs across multiple versions (7.2.X, 7.0.13 LTS), including Zabbix Cloud.
