Volumio 3 restarts over and over every couple of minutes on multiple rpi’s

On multiple pi 4, 8gig ram deskpi boxes, on initial install, and on ota upgrades, server restarts every couple of minutes, with startup chimes. All boxes behave the same, both with plugins and dac enabled, and not enabled. Same boxes worked fine with volumio2.
Is there problem with 8gig ram on this version? I attempted to send log files through /dev option but was not clear to me if this was successful. Did you recieve files from me under this email address?
