Hub 4 Keeps randomly rebooting

Hello

My hub 4 has randomly started rebooting over the past few days. I cannot see any reason why its not hot and the fan has no dust in it. 

Can a VM staff member check things on their end to see if they can see why? 

Below are stats and logs:

Re: Hub 4 Keeps randomly rebooting

Hub stats look fine - is it wireless or wired devices that you are noticing this on?

Just to also confirm I have tried a pinhole reset a couple of days ago.

Re: Hub 4 Keeps randomly rebooting

Funny you ask because I think it was the wireless link from the CCTV camera. I have changed it to a spare VM pod for now and so far it has been stable lets give it a week.
