Recently my Readynas Ultra 6 Plus keeps rebooting randomly every 20min-1hour
So since last week my Readynas Ultra 6 Plus, keeps rebooting every 20min-1hour
I hae searched the forums and found another topic about this, however it is closed and i couldn't respond in it, so there were a few tips or things to do, which i did:
I have cleaned the inside, so there is no heat build up due to dust. I increased my fans to cooler - my fans are running between these speeds
CPU: 1700-1900
system: 840-860
since i bought the device in 2009, the first thing i did was replace the memory to increase it, never had issues with the memory. I have: MemTotal: 4039328 kB
I disabled rsync and antivirus.
I wanted to do a disk test, but because my readynas is always resyncing due to the reboots and reboots again while it is busy doing the resync, so i am unable to perform a disk test
In the logs I only see the resync info and that my storage capacity is below 20% (still have 2.5Tb free)

And there is nothing in the log showing the power off, just a new power on?
A marginal power supply might cause that, especially the +5VSB (+5V Standby), which powers the on/off circuit. That's a common issue with the older NAS models -- the power supply just doesn't last forever. But, it is replaceable with a standard SFX format PSU, though you need a 24-pin extender cable and may need one or more SATA to Molex power adapters or Molex Y cables. If you have a "spare" ATX12V supply, it can be connected externally to see if that fixes the problem before you invest in a replacement (though they aren't that expensive).
While the standard PSU is only 300W, I recommend at least a 350W replacement because the original has more 12V current capacity than a typical 300W. I've used a lot of different versions, since many have come and gone from the market, and usually go with a 400W.
If you want the easiest/cleanest replacement, there is a vendor on eBay that has some that already have the needed cabling.

I think the error code is related to email alerts. Are you using gmail for that? If so, have you switched to using an app-specific password?
On the main issue, I am thinking a factory default is worth a try. This will destroy all your data, so you'll need to make a full backup first.
If you have a spare disk, you could try powering down, and removing all disks (labeling by slot). Then do a fresh install on the spare, and see if that behaves the same way.
Note if this is power-related, passing this test might not prove anything, as a single disk will obviously not load the PSU nearly as much as the full array. But if it fails, you will rule out the disks and software.

I don't know that the memory test would be that good at saying the power supply is OK. Power-up and drive spin-up (if you have spin-down enabled) would be the things that stress it the most.
The first link doesn't take me to an SFX supply. The second does, but it's quite the overkill for a NAS, with a price to match, but it'll work. You may be limited in what you can get in your country. The removable cables does make it a bit cleaner to install, since there are some you can leave off. It does have two 4-pin Molex connectors, so one SATA to 4-pin is all you need in addition to the 24-pin extender (usually about 12cm, I don't know about with this supply).
You didn't answer the question as to whether the power-down events show up in the log.

Yes, you'd be paying a premium for more wattage and "gold" status than you really need with the earlier ones. Of the two you linked, I suggest the Sharkoon, as it has the fan centered. Some have reported here no issue with an offset fan like on the other one, but you would be losing some cooling capability because it'll be partially blocked.

Did you also order the 24-pin extender? I've not seen any stock supplies with a cable long enough, though you can connect it externally without one just to see if it fixes your issue.
