Space Used by the Data Collection Agent's dispatcher queue is at or above the critical threshold. The dispatcher queue will continue to hold items and attempt to enqueue them into the Storage Service at a higher rate than normal to help reduce the backlog. However, breaching the critical threshold implies that normal processing of the data by the Storage Service is slow or blocked resulting in excessive growth of the dispatcher queue. Not only have the number of items and the memory footprint of the dispatcher queue reached a critical level, but also the likelihood that some items have been lost from the dispatcher queue due to a failure to enqueue them into the Storage Service is extremely high.

Name: %1, Item Count: %2
Cause: The dispatcher queue size can grow bigger under heavier usage. However, breaching the critical threshold implies that there is some error with the Storage Service or its dependent components resulting in slow or blocked processing. The likelihood that items have been lost from the dispatcher queue due to a failure to enqueue them into the Storage Service is extremely high. An immediate investigation to find the root cause of this torpid processing of the data is required in order to prevent further data loss and return to a normal state.
Resolution:
The dispatcher queue will constantly attempt to enqueue items to the Storage Service at a higher than normal rate. However, the likelihood of some error in the Storage Service is very high and looking for error events from the Storage Service will provide a good start to the investigation. Taking this server out of rotation might be necessary to prevent further data loss and will help buy more time to resolve the root cause of the issue and let the dispatcher queue reduce the backlog and return to a normal state.
