Sol Huebner commented on NIFI-6414:
-----------------------------------

It seems that with that extra line the NiFi tests fail. I need to spend more time to debug why.

>    Affects Versions: 1.9.2
>         Environment: CentOS 7 with NiFi 1.9.2
>            Reporter: Sol Huebner

> I get "java.net.PortUnreachableException: null" when I use PutSyslog using UDP. I have no issues with TCP. The issue only occurs when you try to use the connection multiple times.
> I found a similar issue here: [http://www.java-gaming.org/index.php?PHPSESSID=u7ufav5hekdirj9991jll36e81&topic=1751.msg16721#msg16721]
> So I tried to modify DatagramChannelSender.java of the nifi-processor-utils:
> if (!channel.isConnected()) {
>  {color:#59afe1}channel.socket().bind(newInetSocketAddress(InetAddress.getByName(host), port));{color}
>  channel.connect(newInetSocketAddress(InetAddress.getByName(host), port));
>  }
>   
>  And with the added line I have no more issues.
