Abstract
A method for facilitating root cause analysis of a software crash by core dump analysis is disclosed. The method comprises receiving a core dump file relating to a software program, identifying unique source code lines in the core dump file for each running thread at the crash time, and determining unique source code lines as conspicuous source code lines depending on an abstraction level value indicating a number of occurrences of the conspicuous source code line in different threads. Furthermore, the method comprises determining an abstraction ratio as a function of a number of conspicuous source code lines and a number of unique source code lines, evaluating whether the predefined abstraction level value has to be adjusted by determining unique source code line as a conspicuous source code line and determining an abstraction ratio, and outputting the conspicuous source code lines and an assessment value for the abstraction ratio.
