Your server has run out of memory, and processes (potentially required) are being killed off. You should post your diagnostics and ask for assistance on the Unraid forums.

 

Please, may I receive assistance?

 

I will reboot now.

 

Thank you in advance.

If it's a one time thing you can ignore, if it keeps happening try limiting more the RAM for VMs and/or docker containers, the problem is usually not just about not enough RAM but more about fragmented RAM, alternatively a small swap file on disk might help, you can use the swapfile plugin:
