Failed Async Completes

Description
This counter indicates the number of times when ASync Read Complete Calls and ASync Write Complete Calls fail. It is a server-level cumulative count and reflects the failures from various OPC DA clients.
If the value in this counter is incrementing, it indicates that a client connection has failed. A FactoryTalk Diagnostics Message is also generated. Verify all client connections.
