Random port banding failure

The application exit due to port binding failure.
I think the port was used serving other traffic, 1000 time trying won't last that long for the port to be released.

I think for the 1000 times trying, maybe we could use different random port instead of same random port?
Which means to move the port calculation into the loop instead of ouside the loop.

Thoughts?

I think you are right. The port calculation was meant to be inside the loop, I cant believe I have put it outside😂

yea, i'm suffering from this issue and almost would like to fork and change myself. I'll submit an MR once I'm available but it would be great if you could update it from master repo. bo wangyu- <[email protected]> 于2018年11月13日周二 下午4:21写道：

Thank you very much.
