I had a second look at this, and realized that those memory mapping settings aren't used from the batch inserter. Everything is allocated in the Java Heap. 63G out of 64G RAM is still a bit much, but not as big of a problem as I first thought.
This also means that there could be another problem behind the exception you receive. There should have been a causing exception for the one you listed. Could you please provide a full stack trace?
