line breakings

[Jefferson Rincón]

Hey. I'm new to Lilypond, but i've been able to make good sheets out of it. 
I have the 2.2.6 version for Ubuntu Linux. I'm writing a percussion score, 
and it's all good until it gets to the 38th bar: it doesn't do line 
breakings anymore. The \break command doesn't work at all. I have multiple 
Drumvoices (if that's got something to do).
This is the output I get:

As you can see, the output is finally printed, but without line breaking 
after the 38th bar. What should I do?
PD: The whole .ly file is attached if that helps.
Thanks.
