I have a UDP server running that uses the Udp.bindFlow(...). On the machine where the software is running, there are sometimes severe network errors leading to failures like the following for the HTTP client: ```Tcp command [Connect(192.168.2.60/<unresolved>:8088,None,List(),Some(10 seconds),true)] failed because of java.net.SocketException: Network is unreachable``` When this happens often the UDP server is not working anymore, but there are no error messages and the stream using the Udp.bindFlow(...) is still running. Only a restart of the software fixes the problem. Today I was lucky that when the problem happened again, I had an incoming UDP request that was exactly answered in that moment and I found the following message in the log: ``` INFO org.apache.pekko.actor.LocalActorRef - Message [org.apache.pekko.io.Udp$Send] to Actor[pekko://uni-meter/system/IO-UDP-FF/selectors/$a/0#2020722919] was not delivered. [1] dead letters encountered. If this is not an expected behavior then Actor[pekko://uni-meter/system/IO-UDP-FF/selectors/$a/0#2020722919] may have terminated unexpectedly. This logging can be turned off or adjusted with configuration settings 'pekko.log-dead-letters' and 'pekko.log-dead-letters-during-shutdown'. ``` I think that brought me on the right track and I had a look to the class UdpBindLogic. There is no death-watch on the bound UdpListener actor. When the listener dies, the stream is basically idle afterwards but no error message is given. I am not a Scala expert, but if desired I can provide a PR to fix the problem -- This is an automated message from the Apache Git Service.
