Crash Dump Analysis Patterns (Part 252)

Some Stack Traces reveal a functional purpose, for example, painting, querying a database, doing HTML or JavaScript processing, loading a file, printing, or something else. Such traces from various Stack Trace Collections (unmanaged, managed, predicate, CPUs) may be compared for similarity and help with analysis patterns, such as examples in Wait Chain (C++11 condition variable, SRW lock), finding semantically Coupled Processes, and many others where we look at the meaning of stack trace frame sequences to relate them to each other. We call this analysis pattern Stack Trace Motif by analogy with Motif trace and log analysis pattern. Longer stack traces may contain several Motives and also Technology-Specific Subtraces (for example, COM interface invocation frames).
