Watchdog Reset

We are getting a lot of random reboots, sometimes four or five times a day, on one of our sectors and the following message appears in the logs:

System Reset Exception -- Watchdog Reset 
Software Version : CANOPY 13.3 AP-AES
Board Type : P12
Device Setting : 5.7GHz MIMO OFDM - Access Point - 0a-00-3e-a2-bb-a2 - 5760.0 MHz - 20.0 MHz - 1/16 - CC 40 - 2.5 ms
FPGA Version : 112414

We also see it occasionally on other sectors.

Has anyone seen something like this and is there something we can do to sort it?

Thanks for any help.


Do you have reset or sync cables run to the APs?  We had a lot of problems with an AP which was synced off a cable, and it kept rebooting and resetting itself.  I ended up redoing the ends and only putting in the wires necessary for sync, and that fixed the issue.

We are using a sync injector on the PoE port for sync. I see that there is a new 13.4 Beta release and it mentions unexplained watchdog resets on the PMP450 as one of the bug fixes. We might give this a try to see if it helps.
