Subject Re: Phoenix Exception - Connection is null or closed.
Date Sat, 24 Mar 2018 15:27:02 GMT

It seems that this exception is not bug,  you should check your code of
logical layer. Sometimes this exception will be trigger when multiple
thread to access connections pool( some connections are closed at that
time).
