Thanks for these advices. I intend to make small investigation about
this case. A will post more information as soon as possible.

Yes, I exactly understand this methodology. Maybe I've used too strong
words, but I mean that the problem is related with udhcpc - not else.
I don't know whether it is a bug or my system is wrong configured. I
just only try to locate and solve this problem.

Thank you very much for interest. I will write more for a few days.
