this short example shows the problem with staves going off the bottom of 
the page:

%=====================
\version "2.13.32"

%#(set-global-staff-size 24.5)

\relative c'' {
    \time 12/8
    \repeat unfold 64 {
        \repeat unfold 3 { c,16 d e f g a b c d e f g }
        \mark\markup { text }
    }
}
%=====================

the console output contains

warning: couldn't fit music on page: overflow is 14.473369
warning: couldn't fit music on page: overflow is 18.535638
warning: couldn't fit music on page: overflow is 0.413630

and staves are going off the bottom of pages 1 & 2. If I add a paper 
block to put page numbers at the bottom of the page and retain a tagline 
on the final page, staves go off the bottom of all three pages:

%=====================
\paper {
    #(define (not-last-page layout props arg)
        (if (and (chain-assoc-get 'page:is-bookpart-last-page props #f)
            (chain-assoc-get 'page:is-last-bookpart props #f))
            empty-stencil
            (interpret-markup layout props arg)))

    #(set-paper-size "a4")
    ragged-bottom = ##f
    ragged-last-bottom = ##f
    ragged-last = ##f
    oddHeaderMarkup = \markup \fill-line { "" }
    evenHeaderMarkup = \markup \fill-line { "" }
    oddFooterMarkup = \markup \fill-line { \column {
        \fontsize #2
        \on-the-fly #not-last-page \on-the-fly #not-first-page 
\fromproperty #'page:page-number-string
        \on-the-fly #last-page \fromproperty #'header:tagline
    } }
    evenFooterMarkup = \markup \fill-line { \column {
        \fontsize #2
        \on-the-fly #not-last-page \on-the-fly #not-first-page 
\fromproperty #'page:page-number-string
        \on-the-fly #last-page \fromproperty #'header:tagline
    } }
}
%=====================
