Chris Hahn sent over this handy warning to be aware of if you are a XenDesktop Admin.
If you are running XenDesktop 7.5, be sure not to leave the Desktop Studio running or it will eventually consume all the memory on your server.
The following discussion notes the error as BUG0455848.
There is no patch available yet but Citrix is aware of the issue. So be sure to only open those admin consoles when you are actually viewing them. :)
