Users of Cyrious Cloud and Remote Desktop may occasionally experience an “Out of Memory” error when running Control or other programs remotely. This is not directly a Control issue, but an issue with the local computer not reserving enough memory to work with RDP.
According to Microsoft Knowledge base article here
Symptom: When you run a large number of Windows-based programs, “Out Of Memory” error messages appear when you attempt to start new programs or try to use programs that are already running, even though you still have plenty of physical and pagefile memory available.
Cause: This behavior can occur if the desktop heap in the WIN32 subsystem is depleted.
Windows 7 Users

Windows 8 Users
If you are using Windows 8, to resolve this problem, you can reserve more memory for RDP sessions information. See the registry entries in the aforementioned knowledge base.
