SSRS - Page Break Issues
The structure of the report is similar to
Main table
Line 1 - Another table with basic data (header type)
Line 2 - Divide into two parts: 1st section has 4 columns, the second section is a table.
Line 3 - Detail table
Line 4 - Footer.
Now there are no page breaks. Somehow after line 2 in some records a page break occurs. The parts table appears on a different page, and the first two lines are on a different page.
The pageBreakAtEnd / pageBreakAtStart properties are false everywhere.
Also, when I set pageBreakAtEnd on the main table, it doesn't work. The next instance of the main table starts from the same page.

Since the renderer can be very touching (for a good reason), you should pay close attention to the overall formatting of any report. Sometimes page breaks (or even page overflows) appear in the strangest of circumstances, many times, because the width of the "page" is too large for the format you are viewing.
This can also happen vertically (what do I think is happening in your situation?), So you might want one of your line elements to be able to express themselves in a way that is much larger than it appears when viewed in a designer.
Generally speaking, you should try to keep things as simple and conservative (in terms of formatting sizes) as possible. One of the most common page breaks / overflow issues is that in the HTML version (via SSRS Report Manager something looks good), but then the slightest border trespass makes the PDF exported version crash.
Also, take a close look at what these page break configuration options actually do. Settings in the report designer can easily cause side effects that reduce other configurations.
