Hello, I recommend running:
lsof -p <nifi pid> This will give you a listing of all file handles that NiFi has open. From that, you should be able to better understand what files (or sockets) are open.

We have followed the only youtube video that we have found to make sure our setup is good. The issue we have is as soon as this processor is turned on, we start seeing the errors of “too many open files handles”. We are running this on a RHEL 7 environment and have set our limiteNOFILE to 100000 in our /usr/lib/system/system/confluent-nifi.service. This seems to work perfect with the dataflow without the executestateless processor. I will try to provide everything I can, but we are running this on a private system so some things will be harder to provide. Any help will be appreciated.
