The Terracotta Management Console flashes warnings if the TSA enters throttled or restricted mode. These modes are initiated if memory resources drop below a certain threshold and endanger the operations of the cluster.

The TSA can automatically recover from throttled mode after sufficient expired data is evicted. Under certain conditions recovery might fail and restricted mode is entered. You can provide temporary relief by clearing or disabling caches. For information about clearing or disabling caches, see Management Panel.

If the TSA enters a throttled or restricted mode, it is an indication that memory resources have been under-allocated. The cluster might need to be stopped and additional steps taken to ensure that enough memory is available to cover cluster operations.
