Public Service Announcement Since I've lost two EXTENDs already to "reset reason = application watchdog" I've been paying closer attention to what my EXTENDs do. Here is what they sit at now (number is the last segment of the IP address): 100, new as of a month or so ago. 19700101-00:00:20 System: reset reason = application watchdog 19700101-00:00:20 System: E5592573 0000000E 004E2D68 0042D3A0 00432724 0040D9D0 004DDCEC 004DDCC0 19700101-00:00:20 System: 00506E0C FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF 19700101-00:00:20 System: network link 100f 19700101-00:00:21 System: ip address obtained: 192.168.0.100 / 255.255.255.0 20180415-06:00:50 System: time changed from Thu Jan 1 00:00:37 1970 to Sun Apr 15 06:00:50 2018101, about 19 months old and the most used of the three. 19700101-00:00:17 System: reset reason = application watchdog 19700101-00:00:17 System: E5592573 0000000E 004E2D68 0042D3A0 00432724 0040D9D0 004DDCEC 004DDCC0 19700101-00:00:17 System: 00506E0C FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF FFFFFFFF 19700101-00:00:17 System: network link 100f 19700101-00:00:18 System: ip address obtained: 192.168.0.101 / 255.255.255.0 20180401-06:00:53 System: time changed from Thu Jan 1 00:00:34 1970 to Sun Apr 1 06:00:53 2018102, about 19 months old and rarely used. System Log 19700101-00:00:17 System: reset reason = firmware upgrade 19700101-00:00:17 System: network link 100f 19700101-00:00:18 System: ip address obtained: 192.168.0.102 / 255.255.255.0 20180328-21:18:07 System: time changed from Thu Jan 1 00:00:34 1970 to Wed Mar 28 21:18:07 2018102 is perfectly fine so not much to talk about there. 100 and 101 both have the application watchdog message; however, note the time it occurred. It's almost like they deliberately rebooted themselves at 6am. The question is why? Did the log get so full it had to purge it? I don't think this behavior is in error because nothing was recording at the time. Still strange and something to be aware of.
