XCP-NG OR XOA Issue?

Maybe someone here has seen this issue. Have an older VM running Server 2008 R2 for older applications. Its in its own little place with no outside connection, but computers can connect to it for certain functions. Now its deprecated, so not that much use, but about 4-6 people connect to it a few times a week and I’ve noticed I have to restart it more often. It looks like it locks up because no one can connect and it spikes CPU usage and disk usage to near 90%. On top of that, the weird thing is, the Memory/RAM usage shows 0%. But, in the system, it shows normal at about 20-40% when in use. Oddly enough, I know I have to restart the VM when the Memory/RAM is at 0% every single time. Its not like its once in awhile that it shows this.

Anyone else seen this issue before?
