Steps to reproduce:

1. Zabbix server update 6.0.13 to 6.0.15

Result:

After upgrading to Zabbix 6.0.15, the values of the following items cannot be obtained.

Context switches per second
Interface enp0s3: Bits received
Interface enp0s3: Bits sent
Interface enp0s3: Inbound packets discarded
Interface enp0s3: Inbound packets with errors
Interface enp0s3: Outbound packets discarded
Interface enp0s3: Outbound packets with errors
Interrupts per second
System boot time
Zabbix server: Number of processed character values per second
Zabbix server: Number of processed log values per second
Zabbix server: Number of processed not supported values per second
Zabbix server: Number of processed numeric (float) values per second
Zabbix server: Number of processed numeric (unsigned) values per second
Zabbix server: Number of processed text values per second
Zabbix server: Number of processed values per second
Zabbix server: Value cache hits
Zabbix server: Value cache misses

I have checked the server and agent logs and there are no warnings.

Expected:
Zabbix server can continuously retrieve item values.

I tried building a new Zabbix 6.0.15 environment on Alma Linux 9, but the same problem occurred.
