Greetings; As I attempt to go beyond the original setup on the pi 3b, which was to run linuxcnc on it.
But since it has 1/2 its cpu power left over, I am finding the lack of memory to be a pita. Starting a camera application so I can calibrate out the errors in the lathes mechanics then kills other services like ssh, or even the whole thing so bad it needs a powerdown reboot. I have a couple ssd's mounted each with a couple gigs of swap, but the pi isn't using them, at least not as expected. What would be the chain of things to check and adjust so it does use the available swap? There is a 10Gb defined in the /etc/fstab, on partition sda2, one of the 2 ssd's plugged into a usb hub. If swapon -a is run, I can see 999megs of swap in htop, which goes away after a swapoff -a, both of course as sudo root. Thanks for any clues. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
