WAC510 Frequent power cycling

I bought a 3 pack of WAC510's. I installed them and am happy with their performance. Up until recently everything worked as expected but i believe since the firmware update 1.2.5.12 my AP's started restarting about once a day and usually in the middle of the day. In the last couple days it happened even more frequently. All AP's have the same and latest firmware.
i checked the logs and this is the only thing i could find that might have seemed a bit abnormal:
"nddmp[2139]: alarm : seqNo-[2], level-[INFO], info-[Reboot reason - WDT]"
i am not sure what the "WDT" stands for and if it is in anyway related to the reboots.
Any ideas and input appreciated,
Edward

At Raghu's suggestion I turned RRM off on both devices and that appears to have done the trick. Both of WAPs have been up for 3+ days with no restarts.
Sounds like there might be a bug in RRM that will get addressed with the next update.
Disabling this hasn't appeared to significantly impact our network performance, although andecodally one android client user is complaining that his device is not acquiring/holding connections as well. Could easily be something else going on there.

Re: WAC510 Frequent power cycling
Thanks Raghu, i have not noticed a recognizable pattern in the power cycles. I did notice that all APs do it at just about the same time. Almost in sync. There are over a dozen devices connected so it is hard to tell whih device or type of traffic this might cause. We do watch Youtube but Skype rarely. There are multiple tablets, phones, 1 Xbox One and a Nest connected to it. There are also some Nest Protect devices connected and some other smarthome devices that don't occupy the APs in the house.
i got the config and log file as a .tar.gz but i do not see an option to upload it
Thanks

Re: WAC510 Frequent power cycling
My devices are wired via poe to a GS108PEv3 and share the same SSID.
I have attempted to identify a pattern but can't see any. Traffic is always very low on our network so it doesn't seem activity related?
It's a significant issue - they are rebooting > 10 times per day.
Log snippet - any way to increase the verbosity?

Re: WAC510 Frequent power cycling
Thanks Dsmalley, i am glad i am not the only one. i also noticed that you have the same message "[Reboot reason - WDT]" in your log.
i hope we can find out what WDT is.
Ssome more info on my APs had firmware 1.2.5.1 to 1.2.5.11 and now 1.2.5.12.
I have one with power adapter and one with PoE.

Re: WAC510 Frequent power cycling
I think "WDT" refers to a "watchdog timer" (see wiki). If so then I think this points to some pile of errors or some other threshold condition that is getting hit making the devices decide to reboot.
Hopefully the support team can figure it out looking at the detailed logs and config and it's just something simple with the setup/config.

Re: WAC510 Frequent power cycling
hi @BoT
Thanks for sharing additional details. I guess power source is not the culprit based on your description (PoE connected/with power adapter)
Have you ever tried any other firmware & see AP is not restarting apart from those you have mentioned? I have sent you PM regarding config and log files.
@Dsmalley Sorry it appears the logs and config file are removed/moved from your shared location. I have PMd you too.
Kindly note that we are actively workig on this issue with top most priority
Thanks

Re: WAC510 Frequent power cycling
Also - I installed kiwi, enabled syslog, and attached that log data as well. It looks like one of the devices restarted 3 times overnight - very low / no activity.

Re: WAC510 Frequent power cycling
Same thing here.
It's particularly annoying because a lot of the equipment that we have will not recoonect automatically.

Re: WAC510 Frequent power cycling
Are you seeing the WAC510 restart and after restart wireless clients do not reconnect to WAC510 . I'm just trying to understand your issue in more detail. Nice if you can add more details
Thanks
