Knuth (or someone else) even talks about the possibility of having a footnote
in a line that will occur near the bottom of the page. When the pages are typeset,
the presence of the footnote forces the page to be shorter, moving the
footnote reference to the top of the next page, so that the footnote would
appear on the page before it is referenced!
But if the footnote is moved to that next page, then the extra space allows
the text with reference to occur back at the bottom of the previous page.

Successive typesets alternate between these two positions.

This is a dilemma that cannot be resolved automatically.

It could be that something similar is happening to you.
The way to fix it is to alter the text in your document to either add or
subtract overall length, without changing the meaning, so that everything
can reach a stable state.

Hope this helps,
