Error description
In response to customer requirements, the *VMEVENT Enhancements line item will deliver new and enhanced event records. New event records are generated to provide data associated with virtual machine console disconnection and reconnection. Logon event records are extended to identify the logon-by user (if any) and to identify the terminal connection. The logoff-timeout-started and logoff-timeout-service event records are enhanced to report large timeout intervals correctly, by appending a 32-bit unsigned interval value to the existing message format. Redundant runnable (Class 0 Type 5) events are eliminated. The runnable event is now reported only when the virtual machine is leaving a non-runnable state.
