This looks like a bug, then - assuming that you were in fact cracking
oracle11 hashes found in or.txt and not something else.  "ls -l john.pot"
before and after the cracking run would be more convincing.  Also, you
could try lowering the "Save" setting in john.conf to something like 10
seconds.

Well, I guess we can live with the fact that MPI support is an unreliable
feature in -jumbo, although I don't mind accepting patches for it.  Like
I said, personally I don't use it and don't recommend it.
