That's correct.

The code is set to dynamically resize the list of forward references. Perhaps
you simply ran out of memory.

That's normal. slapadd doesn't checkpoint the database while it runs, it only
does it before exiting. Since it's common to run it with DB_TXN_NOSYNC it
seemed counterproductive to checkpoint, but perhaps that should be changed.
