hi @micha! I believe one of my collegues has answered your PR, but for the benefit of others reading this: The creation of the caches is triggered either every 60 seconds, independently of polling the data (for systemd based setups) or right after the agent data has been polled (for xinetd based setups).
This means that if your cache interval is smaller than the check interval, you will never get unexpired data in the xinetd case, and in the systemd case only if you’re lucky.
