True - which is why I mentioned it. Though the odds of something going wrong in a migration from RN516->RN526 are pretty small.
But if you have a spare disk handy, it doesn't take long to upgrade the firmware in the RN526 flash first.
Hi pgjscottieuk, this seems to be related to memory page faults and how the linux kernel is handling them. In a nutshell, try testing the RAM to see, whether it might be faulty hardwarewise.
Here is is a link to an article describing in detail how the linux kernel is dealing with page faults and involves fixup exceptions related to this. Once you opened the following link search for "fixup" on the webpage to see it in context.
Kind regards

Hi thank you for reply i need to look into how i do that but since then i have had two more messages
After the first i could not shut down the nas it could not be accessed by browser or RaiDar would not shut down from 4 pushes of the on buttonhad to force shutdown by pressing on button and holding until nas shut down
could not access nas from WOL function had to press start button nas booted up as normal then after about 45mins it went offline again showing another fault on the door panel as follows, pgtable_bad + 35
Again could not access the nas anyway so had to force shut down holding the on button
Tried once more same thing after about 45 mins nas went off line displaying another message as follows
sched_rt_period_timer + 1FS
Perhaps all of these mean somthing to someone Nas is in warranty until 17 Feb 2020
Hi pgjscottieuk, the error "pgtable_bad + 35" also points into the direction of problems with memory to my understanding.
You could start a memory test from the boot menu. Please see info behind the link below. Kind regards

I agree it makes sense to do a memory test - though even if it passes you still might want to request an RMA (via my.netgear.com).
You could also try powering down, removing your disks, and doing a fresh install on a single scratch disk. Set it up to match the services, etc you have on the normal system. Then see if the errors continue.
Hi guys thank you for your input and help ran the memory test first time no errors but then the test took about as long as it had taken for the problem to arise before
Shut down did another memory test straight away and it hung at 99% and 37 errors
