I get this error whenever I change the interval of the Trend data or Parameter values and save the configuration. It does not matter if the value is smaller (4 min) or bigger (6 min) than the offload interval of 5 min. Only when I disable both Trend data and Parameter value offloads and save and then enable these again and save I don't get the notice.
What does this notice mean and how can I prevent it and be sure that everything is working as expected?
Full notice:
Central DataBase Offload threads aren't closed in a timely fashion. Potential issues with offloading rate data can occur. Disabling and enabling offload rate settings is advised.
This is a check that is being done before applying the new settings whenever something is changed to the central offload settings.
It basically checks the health of the rate and snapshot threads. If you encounter this error it might be that the offload threads are either stuck, delayed or just have to offload too much data.
Some things you can do are e.g. as the notice mentions disable the offloading for a while, then enabling it again. Check the SLElement.exe memory it doesn't start to leak. Check no RTE's occur for the offload threads.
