It's one of my best usual case: people are coming to me to see what happened when some server process on production is frozen. Of course, even if logs are written and dumped somewhere, in most cases, they are not enough to detect what happens really.

The same scenario occurs when an access violation is followed by a crash of the process, when we need a post-mortem analysis.

Everybody could tell me that we just have to write such a treatment in C# or Java to get the call stack at this moment, but the subject of this post is not what development language to use but what to do when something like that occurs on a production server.
