Abstract
The present invention relates to a method and system for efficiently identifying errant processes in a computer system using an operating system (OS) error recovery method that identifies if the error caused by the errant process can be recovered and, if so, can recover from the error. The method and system of the present invention operates after standard Error Correcting Code (ECC) and parity check bit methods and systems are unsuccessful in recovering from the error In accordance with an embodiment of the present invention, the method and system includes detecting an error during instruction execution, storing a physical address of an errant process that caused the error, and storing an execution instruction pointer (IP) in an interruption instruction pointer (IIP). The method further includes determining a first virtual address from an operating system mapping table, determining a second virtual address from a translation look-aside buffer, and identifying the errant process, if the physical address and the second virtual address match the physical address and the first virtual address.
