Lighttpd

"kills lighty": i cannot reproduce that - it justs sends no content (and i don't have a problem with that).

and my error.log shows it:

2008-08-18 09:49:50: (mod_fastcgi.c.2579) send-file error: couldn't get stat_cache entry for: /path/to/nonexistent/fileordirectory

So... we need more information to help you. If lighty really crashes a backtrace would be good: http://trac.lighttpd.net/trac/wiki/HowToReportABug

the path looked like 200808061

But first you told us lighty was killed and no error was shown, and now there was a error in the log?...

still no error on the log, I found out the path was invalid. Try
header("X-LIGHTTPD-send-file: 2006330");
?>
and lighty will crash

I get

2008-08-20 18:31:13: (../src/mod_fastcgi.c.2587) send-file error: couldn't get stat_cache entry for: 2006330

And i already told you to provide a backtrace.

when I print {{{X-LIGHTTPD-send-file: books.css}}}
a crash occurs, but with {{{/hello/world/books.css}}}, no crash occurs

I guess you are using

server.stat-cache-engine = "fam" 

Disable it and you should be fine.

Yes, you are correct, disabling it resolves the issue.
