Joe Witt commented on NIFI-13279:
---------------------------------
[~alexs]That graph just shows nifi as a JVM app creating resources on the
heap/waiting to do stuff, and then the heap cleaning up. This is, barring any
additional information, very normal behavior. A sign of a leak would look a
lot more like a graph that is slowly but surely moving up and to the right.
This is just up/clean/down,repeat.
If you use the application you'll see a similar pattern but the floor will be
higher since indeed some data will be retained.
You should be in good shape. Not saying it isn't possible there is a memory
leak but I am saying this does not indicate one.
