raise OSError("No memory to allocate with /dev/vcio")

[rodrigoVM8]

Hello Nikolay, i need an advice. I keep getting this error "raise OSError("No memory to allocate with /dev/vcio")". What can i do to avoid getting that?
Another question, when i run a .gcode file, works fine for like 30 commands then it stops with the instruction on screen. What could be causing that? im using RPI3
