Re: odd error

[Shane Brandes]

I did some more testing, broke the file into thirds and they all compiled reasonably. There was a page limiter in one sub file that might have caused that oddness, because now the complete file goes to Error exit status 1 instead. When testing that third it rendered everything onto one page which produced a wonderfully ugly black blob with traces of music about the edges. 
  The project is more or less completed. I used a simple concatenation to put the 3 pdf files together and managed to complete a small book 170 pages which at this point is only for internal use anyway. And that is better than the 272 pages achieved by simply concatenating all the indvidual pdfs. Maybe down the road I will take another crack at combining files en mass and arriving at a finer control of header data and the various other things that tend to escape from one file to the next. 
 
Thanks,
Shane

It means that starting Ghostscript (or for Ghostscript itself, starting
some other program) has failed because the currently existing programs
already ate all of the available virtual memory.

You can check that this is not due to user limits by calling
ulimit -a
on the command line.  If the possible limits don't look unreasonably
small, you might want to observe memory usage during the LilyPond run.

At any rate, this would likely occur when LilyPond is calling
Ghostscript for conversion of PS to PDF, so it would not be working
actively on the (presumably excessive) amounts of memory it has
allocated.  Increasing the swap space on your machine might solve the
problem.

If you find that LilyPond is using an amount of memory that does not
really make sense in the context of your score, this might point to a
bug (memory leak?).  Finding useful examples for debugging memory leaks
is not simple.
