Crash Dump Analysis Patterns (Part 244)

Monday, October 10th, 2016

Long time go we introduced the notion of Collapsed Stack Trace (Volume 3, page 381) when all functions are removed from Stack Trace (for example, kc WinDbg command) and remaining repeated modules are removed similar to Quotient Trace¬†analysis pattern. It is similar to Stack Trace Signature with frame count set to 1. We originally planned to call this pattern Compact Stack (Trace) and it was on our list of possible future analysis patterns. This came to our attention again while preparing “Theoretical Software Diagnostics” book and we decided to publish it under the name Quotient Stack Trace as a specialization of the more general trace and log analysis pattern.

Such a pattern may be useful for the analysis of module Wait Chains.
