Are you on 32 or 64 bit?
Paste "uname -a" 

I had the same experience on 32-bit a month ago. 64-bit is way way
better supported by the build-farms currently for bug/technical reasons.

If you are on 32-bit you have some choices:
- change to a 64-bit machine
- wait for the builds to be done or someone to fix it
- help us find and restart the failed builds (ask Mark on guix-devel)
- build them yourself and share using ipfs and the wip-branch published
a few days ago. and invite other 32-bit users to do the same.
- sack the packages causing the rebuilds and find alternatives. E.g.
rust is drawn in by icecat. Switch to epiphany, etc.

Gnome perhaps draws in an awful lot of builds. Try xfce or stumpwm which
is way way lighter.

Given that you are the first one to notice/write about this in the
latest few months beside me I guess there are very few 32-bit users in
guixland right now so the best option might be to upgrade to 64-bit and
follow the herd.
