Crash Dump Analysis Patterns (Part 65)

Not My Version is another basic pattern of DLL Hell variety. It is when we look at the component timestamps and paths and realize that that one of the modules from the production environment is older than we had during development and testing. The lmft WinDbg command will produce the necessary output. If there are many modules we might want to create a CAD graph (Component Age Diagram) to spot anomalies. Component version check is one of the basic troubleshooting and system administration activities that will be fully illustrated in the forthcoming book “Crash Dump Analysis for System Administrators and Support Engineers” (ISBN-13: 978-1-906717-02-5). Here is one example (module start and end load addresses are removed for visual clarity):

0:000> kL

msctf    C:\Windows\System32\msctf.dll Thu Nov 02 11:13:42 2006

This pattern should be checked when we have instances of Module Variety and, especially, Duplicated Module. Note that this pattern can also easily become an anti-pattern when applied to an unknown component: Alien Component.
