      Zabbix Agent 7.0.1

      Once the wmi.getall item is added, the agent seems to freeze. No data is collected for the item and it disrupts data collection for other items as well.

      The agent crashes and restarts normally. However, as long as the wmi.getall item is enabled, the agent will crash again. Disabling the item allows it to function properly.

      Agent log ends with:

      2024/12/11 10:16:28.875593 [101] adding new request for key: 'wmi.getall[root\mscluster,"select * from MSCluster_Cluster"]'

      The WMI query runs quickly and returns a relatively small amount of data:
