The SYSTEM maintenance object logs information about system resets, including interchanges. When software encounters a problem with hardware, or with its own processes, and requests a restart to clear the problem, an error is logged under SYSTEM. For example, if there is a loss of clocking in a system with duplicated servers, the system switches to the other clock and then executes a level-2 system reset to recover from hardware problems caused by the loss of clock. Errors logged under SYSTEM can help to determine the cause of a reset. For more information about interchanges, see Troubleshooting duplicated servers in Maintenance Procedures for Avaya Aura® Communication Manager, Branch Gateways and Servers.
