You might be wondering on what are we going to discuss in this article as it is most likely the case that you are seeing the error for the first time. But I found it very interesting, especially the whole debugging process I followed to figure out the actual root cause triggering above error.

I have managed to provide hyperlinks to manual pages or websites for those utilities/terminologies I find may be useful for readers to go through and familiarize themselves with more insights.

I would suggest readers to go through my initial article on socket_wrapper project itself so that next few paragraphs make more sense.Read More »
