memory problem?

[David Bobroff]

I'm having a problem that I don't understand.  I have a file which makes 
a book of etudes.  I'm using a series of \bookpart{} blocks inside a 
\book{} block.  When I try to run the whole thing I get this at the end 
of the terminal output:

Layout output to `ten.ps'...
Converting to 
`./ten.pdf'.../usr/local/lilypond/usr/share/lilypond/current/scm/backend-library.scm:24:15: 
In procedure system in expression (system silenced):
/usr/local/lilypond/usr/share/lilypond/current/scm/backend-library.scm:24:15: 
Cannot allocate memory
bash-3.2# emacs&
[8] 7951
bash-3.2#

I tried to learn if the problem was a particular section of either the 
file I'm using to generate the book or with the definitions file which 
is separate.  I tried commenting out the second half and then the first 
half.  Both halves worked independently without trouble.  When I try to 
run the whole thing I get the above.  The definitions file is 5,000+ lines.

I'm running LilyPond mostly inside coLinux on an XP machine.  I thought 
maybe that could have something to do with this. I tried running the 
same files natively in Windows.  Same result, except that the Windows 
command prompt was not so generous with the mode of failure.  All I got was:

Layout output to `ten.ps'...
Converting to `./ten.pdf'...
error: failed files: "ten"

Ideas?
