----------------------------------------

[~copester]

I did intentionally tried to produce this issue by manually giving the same 
port value to different server when I was not able to reproduce it. 

I was thinking solution over the same line that you have suggested - catch the 
exception and then grab new port from TestUtils port related function for 
retry. One thing we need to take care is - to limit the number of tries 
otherwise in worst scenario it may end up in loop. 

> transient unit tests failures due to port already in use
