Hi, The memory you allocate to NiFi will typically be the maximum heap size for the Java process. If you spawn a separate Python process then it will not be bound by the JVM heap size, so in your example it would come from the 8GB allocated for the “system”.
I would recommend if you see high resource usage on the server again you take note of which processes are consuming the resources.
