Exchange Server Page File error message


I run an Exchange Server 2013 on a 2012 Server and I started to get the error message 906 which says "a significant portion of the database buffer cache has been written out to the system file". I know Exchange is RAM hungry and I have 16Gb of RAM on the server. I could add a little more since it's a VM but I'm not sure if that's the right solution. From what I found online, the right amount of Virtual Memory should be the RAM amount +10Mb which would be in may case 16394. The server has 13966Mb currently allocated but the Recommended size mentioned on the server is 5631Mb. What am I missing here?

Thank you for your help!

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The amount of memory on the server is pointless without knowing the context. If you have 10 users, then 16gb if fine. If you have 2000, then probably not.

It could also be a sign of a memory leak. That is usually caused by a third party tool interfacing with Exchange, causing Exchange to fail to release the memory correctly. AV and Anti-Spam software are the usual culprits.

Are both the host and Exchange fully patched?
