NoteWhen this issue occurs, there is no information that indicates a front-end server is in the Queue Full state in the Event Logs or the Performance Monitor counters. To determine whether the "Queue Full" issue has occurred, you must enable the Lync Server 2013 logging for UserServices. If FailureCode:9 is in the log, the Queue Full issue has occurred. The More Information section describes the simplest method to determine whether the front-end server is in the Queue Full state by using the Centralized Logging Service (CLS).
