It still looks like not correctly ordered by unit address against other
nodes in the file.

Hi Krzysztof,
Probably I am missing something basic here. I am trying to put entries 
addresses that are sorted wrt their current adjacent.

And it looks fine to me.

1c0e000 (current exist)
1dc4000 (newly added)
1dfa000	(newly added)
1e40000	(current exist)
