Text Stops Filling Text Box in InDesign, Leaving Large Empty Space

[Grundoon Groundhog]

Suddenly the text stops filling a text box; a large part of the box remains empty, no matter what I do.

The work around is to fit to text and flow to a new text box which I've put in place, but this may cause extra problems if the preceding text has to reflow. There is no page break I can find (and I deleted them all when I brought the text in from Word).

I am making corrections to this complex document, and this problem just started occurring.

I am attaching a screen capture and the original document. The problem is on page 30 (and others).

Is there "No Break" applied to any unrevealed text?

Do you have Keep Options selected with the paragraph. That can force a new paragraph to jump to a new column or page.

No problem for me:

but I don't have your fonts...

Maybe play / turn off KEEP LINES TOGETHER:

You also have empty Story under your main text:

And someone has overriden Running Header and page numbers TextFrames:

All these paragraphs are set to 

Keep With Next 1 Lines:

Which means they will stay with the next line 

Change it to 0

and they will pull back

Yes, but I don't thinks that's a problem - it would be a problem if all next paragraphs would be one-liners. 

As per my screenshot - there is no gap there. 

But I suspect the problem is with the next pair - 2+2.

They all don't have Keep with Next Line 1

only some of them do

Which is why it looks like it's breaking in strange places. 

It's definitely that setting - 100%

What do you mean "not all"? 

[Eugene Tyson]

Only some of the paragraphs have this set like this
