In my /etc/fstab file I got this line on Slackware 14.1:
$ grep "tmp" /etc/fstab
tmpfs            /dev/shm         tmpfs       defaults         0   0
It is a bit different than your line in /etc/fstab but I don't know if that matters.

OK, so I see three things I can do in this order:
1) Try to build libre office in an other directory than /tmp (because it is a tmpfs) and /home (because it is an NFS share)
2) Try to increase the size of my swap partition (as I have 4GB of RAM, I need a swap space of 8GB instead of 1GB)
3) Try to buy more RAM in order to get 8GB instead of 4GB
