  • Automatic support system and method based on user submitted stack trace
    Patent number: 5928369
    Abstract: A system and method for automatically analyzing a program system error. In one embodiment, the present invention electronically receives a stack trace of a program which has suffered an unknown system error. The present invention then compares the electronically received stack trace with a reference stack trace having a known system error associated therewith. In so doing, the present invention determines the similarity between the electronically received stack trace and the reference stack trace. When a predetermined degree of similarity exists between the electronically received stack trace and the reference stack trace, the present invention automatically reports information about the known system error associated with the reference stack to the address from which the electronically received stack trace was sent.
