Running out of memory when there is plenty

[Yzord]

I have installed 4.2 on a server with 128GB of memory. I made 2 nodes on it with each 64GB op memory. Each node is using 4GB of it.

But my monitoring tool is constantly complaining about low memory. Of course i understand that all the memory has been given away to the two nodes, but they only use 8GB of it.

Is there a way to show the precise used memory by the nodes and flowing the other available ram back to the master node? Of course they would be still reserved for the two nodes, but my monitoring tool stops whining about low memory all the time

Both nodes run Ubuntu

It depends on how your monitoring tool interprets stuff. You need to post at least the "free -m" output and maybe "ps uaxwww | grep kvm" output.
