Randy,

In Java 7 this setting can be quite valuable.  In Java 8 it goes away since the purpose of the permgen gets absorbed into the Heap.  Extension bundles which load a ton of classes and other things can certainly tip the scales.  We're at the point now with the set of extensions at play that it can quickly get the permgen full.  Let us know if setting those values gets you back on track.

Thanks
Joe

> Running NiFi built from master this afternoon, using Java 1.7.0_79 on OSX.
> The flow pulls JSON from a web endpoint, splits into about 200 JSON objects which are passed to ConvertJSONToSQL and eventually to PutSQL. Based on nifi-app.log, ConvertJSONToSQL is causing an OOM.
> This same setup works fine on Centos 6.6 with Java 1.8.0_40
