Abstract
A method and apparatus for error detection in a network computing system having a main storage capable of connecting to at least one application server and an interface element with at least one adapter capable of establishing processing communication with at least one application user(s). Data is transferred across the interface element to and from the main storage. The main storage includes a queuing mechanism providing a plurality of queuing components having attributes of devices to and from which data is to be transferred or received as well as information about the queuing mechanism itself. As part of the queuing component, providing a Storage-List-State Block (SLSB) having state indicators that provide state information about a plurality of buffers that make up each queue. A plurality of Error States is defined for by the SLSB Status Block. These Error States are set in the SLSB each time the interface element detects errors in the data stream. By monitoring the number of the errors for a specified time period, it can be determining as whether a session needs to be terminated or kept active.
