Comment 1 for bug 1737892

I was trying to understand from gate logs what is the reason of this issue and was also trying to reproduce it locally.
It looks for me that it is kind of race when load on test host is big because there is very short time between adding port and removing it.
I was able to reproduce this issue manually once. I will keep digging into it to confirm (or not) if that is really reason of this issue.
