What is the best bug repellent product?

What are the situations or  under what conditions does a software engineer who is exceptionally good in software technologies and programming, cannot identify the root cause of a bug which cannot be reproduced consistently in a software product?

  • I'm asking this question because, i have raised a bug regarding the build generation taking very long duration than expected on the product that our company is developing. The developer says that "this issue has come into our list but we cannot identify the exact reason because this issue is occurring inconsistently on very few systems". So i wanted to know whether it is his inefficiency or could there be any such scenarios in the real software world where a software developer cannot identify the root cause of the bug.

  • Answer:

    Any bug, which does not have a proper series of steps which always reproduces it - can be only isolated by either chance or trial-and-error, both of which does not depend on the competence of the debugger. Only if there is a way to consistently reproduce it, then it can surely be resolved or worked around by an intelligent mind.
