This is unlikely to be a bug, and typically points to your memory being full. Can you try again and keep an eye on memory consumption?

Once confirmed, you can consider whether there's other processes competing for resources that you can stop, whether you can reduce memory consumption of this process (e.g. by reducing batch size), or whether you should consider using a machine with more RAM.
