It is probably RAM size issue. What is minimum RAM for running plutus-playground-server on Ubuntu VirtualBox?

user2335: As all answers, it depends on your setup. Currently I run the plutus-playground-server setup on a VM with 8gb of ram available (but the playground only uses 1gb of that space). The thing to consider and optimize is the way you run you VM. I run my VM with the libvirt stack (this hypervisor runs near native hardware speeds, very lightweigth). Also I do not render a DE on my VM. I just SSH into the VM and only use the terminal, this also saves a lot of ram usage. So I guess that 2gb will suffice bare minimum (I have not tested this).
a good guide for this hypervisor: https://octetz.com/docs/2020/2020-05-06-linux-hypervisor-setup/
Good luck!
