KB 2212 - Failed to update cluster pre query cache status
This is an internal error and implies that the ScaleArc sqlite configuration is out of sync with the UI. Please try refreshing the UI page and try the operation again.
If it's a sqlite database lock issue, it would imply that some other API or service is holding a lock on the configuration database. In that case you can wait for a few seconds for the lock to be released, refresh the page and try the operation again. Alternatively, if the problem persists, you can go to Settings and then System Settings page and click on the 'Reset Configuration Lock' button.
