WAC505 Locks Up And Then Reboots Saying Reason "Normal"

Hi, only had one of these for a few days to test and for the first few days it has been fine.

However, today I noted all the clients attached moaning about the access point missing and when I looked at the device all but the 5Ghz light was on solid with that one off.

Checking the Netgear POE switch powering it was still on the network (I thought perhaps the switch would let me turn off the POE but no option),

The web interface did not work but then I noted its lights were flashing again.

I have not made many changes to the default settings except two extra SSID's

The onscreen log says this

Sun Sep 24 11:42:23 BST 2017 nddmp[2276]: alarm : seqNo-[1], level-[INFO], info-[System UP]

Sun Sep 24 11:42:23 BST 2017 nddmp[2276]: alarm : seqNo-[2], level-[INFO], info-[Reboot reason - Normal]

Sun Sep 24 11:42:23 BST 2017 nddmp[2276]: alarm : seqNo-[3], level-[INFO], info-[Radio 2.4GHz On]

Sun Sep 24 11:42:23 BST 2017 nddmp[2276]: alarm : seqNo-[4], level-[INFO], info-[Radio 5GHz On]

And I have a feeling when it reboots it does not keep the older log, incase it does, I exported the full log.

EDIT: Log file format not acceptable by forum :(

It is on the lastest firmware 

Any thoughts?
