The present invention manages information about support incidents on a computer. The system includes at least two electrically actuated proportional flow control valves connected to each port of the cylinder for selectively and proportionally controlling fluid flow into and out of the at least one chamber. A stall controller unstalls processing of the graphics data in the graphics rendering pipeline when a display interval complete signal has been generated. A reset circuit resets the integrator based on the oscillation detection signal. Using a substantially equal priority value in the reclassification establishes at least a consistent, end-to-end quality of service for each packet that has traversed the long haul portion of a communications network.
