About NC_REVERSE_QUEUE param

I found that the parameter setting value in the file(session_p.h) is 5. What is the reason for this? Will there be any problems if a large number of devices are connected concurrently?

Why the interest in a random internal macro, have you checked where it is used? In short, ignore it, it is extremely unlikely it will affect you in any way.

The reason why I became interested in it is because we encountered the problem of tcp accept queue overflow. This parameter affects the size of the full connection queue, so I want to know what is the basis for setting this value?

I see, there is no special reason for the value. When implementing it (a long time ago) I saw 3 being used so I opted for a bit higher number to be safe. As long as you application is accepting new connections often enough, I do not think the queue can ever reach the limit.
