How do you reproduce bugs that occur sporadically?

Question

We have a bug in our application that does not occur every time and therefore we don\'t know its \"logic\". I don\'t even get it reproduced in 100 times today.

It's quite common for programmers not to be able to reiterate a user-experienced crash simply because you have developed a certain workflow and habits in using the application that obviously goes around the bug.

At this frequency of 1/100, I'd say that the first thing to do is to handle exceptions and log anything anywhere or you could be spending another week hunting this bug. Also make a priority list of potentially sensitive articulations and features in your project. For example : 1 - Multithreading 2 - Wild pointers/ loose arrays 3 - Reliance on input devices etc. This will help you segment areas that you can brute-force-until-break-again as suggested by other posters.
