Detailed Description

Generated when an internal queue of a MonitoredItem subscribing for Events in the Server overflows.

This EventType inherits all Properties of the BaseEventType. The SourceNode for Events of this type shall be assigned to the NodeId of the Server object. The SourceName for Events of this type shall be “Internal/EventQueueOverflow”.

This Event is generated when the first Event has to be discarded on a MonitoredItem subscribing for Events. It is put into the Queue of the MonitoredItem in addition to the size of the Queue defined for this MonitoredItem without discarding any other Event. If discardOldest is set to TRUE, it is put at the beginning of the queue and is never discarded, otherwise at the end. An aggregating Server shall not pass on such an Event. It shall be handled like other connection error scenarios
