[~exceptionfactory] i have same issue after upgrade from 1.16.0 to 1.17.0. I'm using keep alive and rsa keys. My nifi is standalone version on centos7, i'm connecting to tens of different sftp servers. Can i help you in any way to reproduce issue?
This is blocker for me to use 1.17.0 version cause i am not able to monitor real connection problems with so much false positive alerts.
