I could be totally barking up the wrong tree, but I think this is our clue: Requested array size exceeds VM limit
That means that something is causing the reader to try to allocate an array with a number of entries greater than the VM allows. Without seeing the schema, a sample of the CSV and a stacktrace it's pretty hard to guess what's going on. For what it's worth, I've split 55GB JSON sets using a custom streaming JSON reader without a hiccup on a NiFi instance with only 4-8GB of RAM allocated, so I'm fairly confident we've got some quirky edge case here. If you want to sanitize some inputs and share along with a schema that might help.
