I agree with demazter, looks like you have a bad program that is leaking or not releasing memory properly. &nbsp;Create a script to do a nightly reboot of your servers and see if the &quot;issue&quot; &quot;goes away&quot;.

A lot of HP drivers suck on Citrix servers, especially their universal driver.
