Oleg, Like I said, I made no change to the logback.xml file at all when the excessive logging happened; it is the default one. I am able to stop the excessive logging by set the following logger from INFO to ERROR level
<logger name="org.apache.nifi" level="ERROR"/> But this fix is not good enough as I do need to see the INFO entries of classes other than org.apache.nifi.StdOut. The only thing I did before the excessive logging occurred was to modify the canvas, changing the data flow. I guess I just have to find the cause myself, because others may not be able to reproduce the issue. Thanks anyway.
