Yep, I believe Volumio’s nodeJS core won’t do very well on 256MB of RAM…

Volumio requires at least 512MB of RAM, 1GB is strongly suggested.
It has nothing to do with Nodejs but with the fact that Volumio loads the entire OS in RAM to avoid SD Card corruption and improve performances, so ideally RAM should be 2X the OS Size (which is rougly 500mb)

I missed this previously, but I don’t think I fully understood your statement…

Where is the loading the entire OS to RAM done?
I always thought it was just a standard SquashFS + OverlayFS?

I realised I still possibly don’t understand bits and bobs of Volumio, in spite of poking at it for a bit now

@volumio @gkkpch Perhaps something to consider when moving the OS porting guide to the new developer docs?

Indeed! That would be really needed…

But I still don’t see where this “Loading entire OS to RAM” is done… Could someone point me to where this is done? Surely you don’t mean the initramFS?
