Today has wrapped up with repeated DNS failures from my PFSense boundary router. I’ve been trying to diagnose things for a good chunk of the evening and so far have little to show for it.
I’ve played with the DNS configuration and things don’t seem to have gotten better. I’ve got a fan blowing on it…temperature is down but it is still flaking. I’ve reseated the memory and SSD and so far it hasn’t failed again, but I’m still concerned.
I did finally order another similar small machine to act as either a replacement or a spare. The household firewall is one of those things that will really impact everyone here should it go down for a period of days (hours is bad enough) so the spare will be welcome.
Hoping to figure this out in more detail sometime soon. I am expecting to have an external fan blowing across the ‘fanless’ computer from now on to keep the temperature down and hopefully forestall any future problems. It had been getting warmer than I liked, but not so warm that I felt there was likely to be an issue…more to come as I work through this over the coming weekend…
