I did a jhalfs build yesterday and got 2 unexpected successes and no 
unexpected failures for gcc-4.9.2.

I used -j10 and it completed in Totalseconds: 1252 (about 21 minutes).

I'll just state the obvious.  Did you run out of ram?  Is it in chroot? 
  Are all the virtual filesystems available?

I can send you my logs if you want.

Hmm.  My last build had:

du -sh firefox
4.6G    firefox

That was version 32.0.1 on one system.

2095.7 Elapsed Time -  firefox-32.0.1.source
146524 /usr/src/firefox/firefox-32.0.1.source.tar.bz2 size (143.089 MB)
4823172 kilobytes build size (4710.128 MB)

Do you need me to do the latest for comparison?
