Re: warning: compressing over-full page by 12.4 staff-spaces

Hi,

first on a technical note: Many do not use the Nabble interface and they 
can’t see to which old thread you are replying. It’s more helpful to 
just open a new one.

The problem doesn’t ring any bell with me, at least with the empty space 
you are referring to. You could try inserting the following line into 
your LilyPond file to enable visualisation of the ‘skylines’ LilyPond 
uses for spacing:
#(ly:set-option 'debug-skylines #t)
and report back if that gives any hint, maybe as to what grob is causing 
the empty space.
Else it’s not possible to say anything without looking at the actual 
code. Either you have another go at creating a minimal example, e.g. by 
successively replacing music with spacer rests, or using explicit page 
breaks, or \repeat constructs. Or you send over the whole file, 
privately to me if necessary.

Best, Simon
