Out of memory isra 13+31c and RNDP4000 Lock up after upgrade to OS6 from OS4
after an initial successful upgrade from OS 4 to 6.1 and 4 x 8TB drives we've begun to experience access issues with our Readynas Pro 4 (RN). The error is repeatable as per the five steps outlined be...

Have you considered upgrading the memory on the Pro?

It's been a good few months since we last posted which has seen our RN sat in the corner gathering dust primarily due to the locking up issue and losing complete interest/adopting an alternative backup strategy. We approached the RN again today as a last ditched attempt thinking we'd try updating to 6.8.1 and if that doesn't help then we'll reset and go back to OS4. Sadly despite the upgrade to 6.8.1, disabling quotas along with checksums, this has done nothing to solve our problem. We'd prefer not to spend time fiddling around trying to get this to work but before we reset with OS4 and begin copy everything over again, are there any firm suggestions, sure-fire fixes or specific logs to examne that others have had where they've experienced the locking up/out of memory issue BUT actually managed to fix it?
Thanks

We did read up on a possible CPU/Memory upgrade a while back and it appeared that a Core 2 E7600 cpu and memory with timings of 5-5-5-15 were recommended. Is that still the case and besides the Crucial CT2KIT25664AA1067 (PC3-8500 1066MHz Memory) which popped up a few times what memory would you suggest please?

I went with Patriot memory a while back in my Pro-6, and it is working out well ( https://www.amazon.com/Patriot-Signature-Memory-Module-PSD28G800K/dp/B004ZG20C6 ).
But I am using the stock CPU. If you are using the NAS purely for storage, then I don't think you need to upgrade the CPU.

thank you for the patriot link. this appears to be ddr2 whereas the pro 4 is listed as having a single stick of ddr3 which we didn't think (despite it working well on your pro 6) were interchangable? what's the maximum memory the pro 4 can accept and are we right in thinking it only has one slot?
the pro 4 is listed as having the atom cpu which again from reading didn't appear to be upgradable but we're happy with how it used to perform prior to locking up so no need to touch this
