Blueworx Voice Response telephony activity is unexpectedly disrupted

On a production system, you should disable any screen savers (otherwise known as screen blankers). A screen saver is an application that is activated after a specified period during which no user interaction with the mouse or keyboard occurs; it is deactivated when you move your mouse. When it is deactivated, a significant amount of X activity occurs at very high processor priority, causing major disruption to Blueworx Voice Response telephony activity. Calls in progress are interrupted because trunks and channels are temporarily disabled. Normally these effects occur only after a long period of screen saving (an hour or more), but it is sensible to disable any screen savers, such as the standard desktop screen saver that comes with AIX, on a production system.
