Error description
The DMI visibility queues used to write communication events to the database can block sometimes. visibility.log.D20160623.T084929:[2016-06-23 08:54:39.714] ALL DmiVisEventWarehouseQueue.Worker - ALERT RESCINDED - AFT Warehouse input BoundedQueue operates below capacity. The normal batch sleep interval is re-established. visibility.log.D20160623.T084929:[2016-06-23 08:55:54.744] ALL DmiVisEventWarehouseQueue.Worker - ALERT ISSUED - AFT Warehouse input BoundedQueue reaches 90% capacity. The Warehouse temporarily suspends to drain the events from queue. The sleep interval to drain the queue to avoid any abrupt shutdown of DMI event processing. visibility.log.D20160623.T085603:[2016-06-23 08:58:24.804] ALL DmiVisEventWarehouseQueue.Worker - ALERT ISSUED - AFT Warehouse input BoundedQueue has reached capacity. Client threads are blocking. The Warehouse will temporarily suspend The sleep interval and work full time to handle this spike in event activity. visibility.log.D20160623.T085603:[2016-06-23 09:01:15.065] ALL DmiVisEventWarehouseQueue.Worker - ALERT RESCINDED - AFT Warehouse input BoundedQueue is operating below capacity. The normal batch sleep interval is now re-established.
Local fix
RTC - 503268 Workaround: Increase the size and number of the DMI visibility queues can solve the problem if the communications sessions originate from different adapters and users. However under certain conditions only one queue is used. For example if multiple SFTP operations are executed during the same session only one queue will be used.
