Hi there, I am using a ListenTCP to capture data coming from an Arduino on a TCP port over WiFi.
When there is a loss of comms over wifi for various reasons (loss of signal, power cut), the Arduino is programmed to attempt to connect back when connection is restored. I am seeing at times the max connections warning as the arduino attemps to reconnect, and it is unable to regain data flow for a long time - it seems to be a random amount of time from a few minutes up to half an hour. I have had a look at this article https://community.hortonworks.com/questions/90478/how-to-release-occupied-connections-in-listentcp-p.html which suggests that the Arduino side should close the connection, however during an abrupt connection loss, NiFi would not be able to detect a closure. Does anybody know if there is a set timeout period on the max connections condition? Is there a way to control how the max connection warning is triggered?
