2012 HYPER-V RAM Usage

I have a hyper-v cluster with 3 2012 nodes. One of the nodes is reporting to be using 97% of RAM.

- There is 250gb of RAM on the server.
- The VMs on this host only amount to 100gb of RAM
- The server itself only appears to be using 6gb.

For whatever reason, I am finding it close to impossible to account for all RAM usage. Resource monitor doesnt help here either

Ideas?

Any backup jobs running?
Snapshots?
Are all host the same make, model and config?

It was cached memory that was eating it all and after logging with MS they have identified this as a memory leak that is a known issue with Hyper-v. We have applied their patch and everything is looking normal now.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

What was the hotfix number please? I would like to research the problem (I'm a Cluster MVP that builds Hyper-V clusters).

Here it is. I think it's been released into the wild now so if your new Hyper-V installation is fully patched you shouldn't see any of the issues we did:
