Hello Team, We are using TCP Processor to receive input from external systems.
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_campai gn=sig-email&utm_content=emailclient> Virus-free. <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai gn=sig-email&utm_content=emailclient> www.avast.com --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
