Updating Memory on Relay Streaming Server\VM

I am increasing the memory on my relay server on my XCP-Ng hypervisor I use to stream the music, and this will require a reboot. While the system reboots no one will be able to connect with the music streams though the songs will continue playing and the website will not go down. The increased memory will lessen swapping of resources to hard drive and increase performance.
Since I’m rebooting for memory update, I decided to install some OS patches as well. Music stream connections will be back up shortly.
