Hello Bryan, Thank you very much for your response.
We thoroughly checked the client piece of the code about managing the opened connection. TCP Processor feeds the incoming data into Kafka Queue to inject the data into our system. Do you suggest is there any known issue in NiFi (0.6.1) version, do you suggest upgrade the version may solve this issue?

When this counter exceeds the number configured in the processor, then it rejects the connection with the message you are seeing. Since you have the max connections set to 1000, there must be over 1000 connections being opened. You could probably use something like nestat or some other networking monitoring utility to see what connections are open. Also may want to look into whatever the source of the connections is to see how it is opening and closing connections.

We are frequently receiving max connection timeout exception We feel the number of configured connections are more than our requirements. Is there any way to monitor the open connections. How we can know that open connections are not closed after data is received from external systems? The NiFi version is 0.6.1 Please find the log file for the reference Exception: Rejecting connection from /162.244.250.137:25558 because max connections has been met Attached log file and processor properties Thanks and Regards, Rajesh Biswas | +91 9886433461 | <http://www.bridgera.com/> www.bridgera.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient> Virus-free. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient> www.avast.com -- Sent from Gmail Mobile --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
