Uptime is 0 weeks, 1 day, 9 hours, 35 minutes, 12 seconds
Explanation: The system uptime counter that keeps track of the IPS runtime, rolls over after about two years and four months. This action, resets the uptime counter of the IPS to zero and makes it appear that the unit has rebooted. This reset action is normal for a system that has not rebooted in over two years. However be aware that during normal IPS device operations, rebooting the system is part of software upgrade process and if routine updates are performed, this issue should not present itself.
