Abstract:
1. A computer-implemented method for determining a similarity between a first error report and a second error report, the similarity being useful to determine whether the first and second error reports were generated by a same error, the method comprising: operating at least one processor to perform acts of: (A) receiving the first error report and retrieving from at least one storage medium the second error report, each error report comprising a callstack and each callstack comprising a series of frames, each frame corresponding to an operation performed by a process; (B) comparing a first series of frames for the first error report and a second series of frames for the second error report, including: (C) applying a corresponding weight from a set of weights to each count in the set of counts to determine a set of weighted counts; (D) summing the set of weighted counts to determine a sum of weighted counts corresponding to a comparison of the first series and the second series; and (E) determining the similarity between the first error report and the second error report based at least in part on the sum of weighted counts.
