Trace Analysis Patterns (Part 72)

Sometimes we look at a trace or log and instead of Error Messages we only see their “signs” such as a DLL load event for an error or fault reporting module or a module that is related to symbol files such diasymreader.dll. We call this pattern Hidden Error by an analogy to Hidden Exception in memory dump analysis pattern catalogue although sometimes we can see such modules in memory dump Module Collection. For example, the presence of diasymreader module may signify an unreported .NET exception and suggest a dump collection strategy.
