I notice that resource usage is not displayed correctly for the subscription in Operations > Subscriptions > example.com > Resources.
I found that "Sync resource usage" task under System > Task Manager > Periodic fails with error:
Resource 'Number of MySQL databases' overusage attempt (subscription #2, usage 3, limit 1).
Limit for the "Number of MySQL databases" resource was lowered for the subscription with ID #2.
You should delete some databases or increase resource limit:
Go to Operations > Subscriptions > Subscription with ID #2 > Resources > Edit and increase limit for the "Number of MySQL databases" resource to current usage at least.
- Rerun failed "Sync resource usage" task and make sure that task is completed successfully.
