Why is all of my RAM cached in OpenVZ?

[KuJoe]

Very strange, I've never seen Linux cache 100% of the memory used. For example, out of 1024MB total RAM I have 295MB of RAM used, out of that RAM being used 295MB is cached. So in theory, my OS is not using any memory nor are any of my applications right? Why does my cached RAM in "free" always show the used RAM?

# free -m              total       used       free     shared    buffers     cached
Mem:                    1024        295        728          0          0        295
-/+ buffers/cache:                    0       1024
Swap:                      0          0          0

Such questions are better posted on the openvz lists/forum.

But this appears to be specific to ProxMox (out of 500+ VMs, only 2 of them are experiencing this issue and those 2 are hosted by ProxMox).
