Memory Leak with clipboard function XenApp 6.5

I have an issue with a Windows 2008 R2 virtual server (with 20GB memory) running XenApp 6.5 - server is hosted on VMware platform.  
I have published a desktop to a user who is copying contents of a PDF via Adove Reader via the 'take a snapshot feature' and pasting directly into a Word 2010 document.  During this workflow the memory on the host server build to 75% and is not recovered after the user logs off.  I have been monitoring using process explorer and the memory usage processes only add up to around 4GB but shows 'physical usage' as 75% (of 20GB memory the server has).  
Does anyone have any suggestions on how to go about fixing this?  Thanks in advance for your advice.

Update: Have just run Sysinternals RamMap and found 13GB used by 'Driver Locked' - I see this could be related to VMware Tools.

If you take an image then it is going to use a lot of RAM.  i guess a lower screen resolution will save ram, but the finished results will look awful.

Copy/paste the text will be efficient, and if you are pure text will be MUCH better since you save the text, not images of the text, so you get whatever resolution you want.  

Use a different screen capture that saves images as a .png is my recommendation, PDF is appropriate for text, not images, and if I interpret the question properly, they are pasting images of the document.

Thanks for the reply.  I'm trying to get around this without asking the client to change their workflow at the moment if I can, as they do this process multiple times during the day.
I just uninstalled VMTools as per another suggestion I saw elsewhere here:  Q_26259037
The problem goes away, however VMTools really is needed as well, I had the latest version installed but the problem persisted. ESX hosts are also latest versions in a cluster environment - I do not manage these so would have to request any changes.
One solution I see was "set RAM resources to unlimited" - I'm unsure how to go about this.

The problem is RAM.  You can be more frugal with it by using different software, or add swap/pagesys to increase virtual, virtual memory ... but the bottom line, is that this particular user needs more RAM to do her job.

Just give it to her. Upgrade the hardware if necessary.   You'll spend a lot more company money and time messing with tuning things to get an incremental improvement then if you just throw $100 or so at it (or maybe much less if this isn't using ECC and you have free slots).

Sometimes the best course of action is to solve the problem, instead of jumping through hoops trying to tolerate it for a short time.

We gave up on 64-Bit deployment as too many issues occurred and we were pressed for time - swapped back to 32-bit. More or less gave the existing environment a new lick of paint and gave it back to them.

Thanks for comments guys, I guess it must be VMWare related issue although they pointed to Microsoft.

The author asked "Does anyone have any suggestions on how to go about fixing this? "  - My suggestions in #38322175 and #38323095 contained numerous workarounds from adding more ram to using a different methodology.  

Bottom line, the system is clearly starved for RAM, so you either use less RAM by doing it differently, or add $20 worth of RAM and move on.  Either way, asked and answered.
