In as far a i can infer, this bug happens because it is stuck in the
infinite loop at logfs_write_anchor() in journal.c

	super->s_no_je = 0;
	for_each_area(i) {
		if (!super->s_area[i]->a_is_open)
		super->s_sum_index = i;
		err = logfs_write_je(sb, logfs_write_area);
		if (err)
			goto again;
	err = logfs_write_obj_aliases(sb);
	if (err)
		goto again;
It is stuck in the goto again loop.
