Seems I now have 5 AP's doing watchdog resets. Sometime every few hours, sometimes every day, sometimes every few days. Fix is to downgrade to 13.2.1 System Reset Exception -- Watchdog Reset Software Version : CANOPY 14.1.1 AP-DES Board Type : P12 Device Setting : 5.7GHz MIMO OFDM - Access Point - 0a-00-3e-b1-2a-30 - 5830.0 MHz - 20.0 MHz - 1/16 - CC 13 - 2.5 ms FPGA Version : 110815 FPGA Features : DES, Sched, US/ETSI; 03/25/2016 : 02:53:21 PDT : :Time Set 03/25/2016 : 02:53:31 PDT : Acquired sync pulse from Power Port. 12/31/2010 : 17:00:00 PDT : : 01/01/2011 : 00:00:00 UTC : :Time Set 12/31/2010 : 17:00:00 PDT : ******System Startup****** System Reset Exception -- Watchdog Reset Software Version : CANOPY 14.1.1 AP-DES Board Type : P12 Device Setting : 5.7GHz MIMO OFDM - Access Point - 0a-00-3e-b1-2a-30 - 5830.0 MHz - 20.0 MHz - 1/16 - CC 13 - 2.5 ms FPGA Version : 110815 FPGA Features : DES, Sched, US/ETSI; 03/25/2016 : 04:26:17 PDT : :Time Set 03/25/2016 : 04:26:24 PDT : Acquired sync pulse from Power Port. 12/31/2010 : 17:00:00 PDT : : 01/01/2011 : 00:00:00 UTC : :Time Set 12/31/2010 : 17:00:00 PDT : ******System Startup****** System Reset Exception -- Watchdog Reset Software Version : CANOPY 14.1.1 AP-DES Board Type : P12 Device Setting : 5.7GHz MIMO OFDM - Access Point - 0a-00-3e-b1-2a-30 - 5830.0 MHz - 20.0 MHz - 1/16 - CC 13 - 2.5 ms FPGA Version : 110815 FPGA Features : DES, Sched, US/ETSI; 03/28/2016 : 08:59:17 PDT : :Time Set 03/28/2016 : 08:59:22 PDT : Acquired sync pulse from Power Port. 12/31/2010 : 17:00:00 PDT : : 01/01/2011 : 00:00:00 UTC : :Time Set 12/31/2010 : 17:00:00 PDT : ******System Startup****** System Reset Exception -- Watchdog Reset Software Version : CANOPY 14.1.1 AP-DES Board Type : P12 Device Setting : 5.7GHz MIMO OFDM - Access Point - 0a-00-3e-b1-2a-30 - 5830.0 MHz - 20.0 MHz - 1/16 - CC 13 - 2.5 ms FPGA Version : 110815 FPGA Features : DES, Sched, US/ETSI; 03/30/2016 : 20:02:15 PDT : :Time Set 03/30/2016 : 20:02:19 PDT : Acquired sync pulse from Power Port. 12/31/2010 : 17:00:00 PDT : : 01/01/2011 : 00:00:00 UTC : :Time Set

I guess that didn't format the way I thought it would

Hi, 

I can see that you are seeing these watchdog resets on 14.1.1. This is something we are fully aware of. Can you please load 14.1.2 (Build 8) on your AP and monitor it. We believe we have addressed silent watchdog resets on 14.1.2-B8. 

You can grab 14.1.2-B8 here: https://support.cambiumnetworks.com/files/pmp450/beta

Thanks,

Sriram

So far so good. 10 hours uptime on 14.1.2 (build 8).  No watchdog resets.

Thanks for the update Michael. I'm glad the fix is working for you. Please upgrade all five of your APs if you feel confident about the fix. We have gotten positive feedback from several other customers on the fix in 14.1.2-b8. 

Thanks,

Sriram
