Memory Inconsistency in GUI and CLI

[gutter007]

I'm running Proxmox 2.0, and I'm really confused by looking at the available memory.

When I log in to the GUI interface


RAM usage 94 GB Total
40 GB Used

When I logon to the physical host:
root@strongest:~# free -g
total used free shared buffers cached

	total	used	free	shared	buffers	cached
Mem	94	94	0	0	1	54

Why is there a large difference between these numbers? Is all my memory being used?

thanks.

linux tends to reserve all available memory, which is what you see there. the amount of memory still available to processes is the sum of buffers+cached in the free output.

And by utilizing some math you can see that 94-54 = 40 which is the amount of memory the GUI reports to be actually in use
