Resource usage excessive after 'guix pull'

Resource usage excessive after 'guix pull'

[Felix Lechner via Development of GNU Guix and the GNU System distribution.]

Hi,

Today, a 'guix pull' caused an excessive allocation of system
resources locally. I had rebased and published an experimental branch,
which only added a targeted (and tested) fix for 'eudev' [1] on top of
the mainline commit e499cb2c12d7f1c6d2f004364c9cc7bdb7e38cd5. Then I
issued:

  guix pull --disable-authentication --allow-downgrades

That command ran very slowly and then resulted in the following
process taking up over 91% memory before being terminated manually via
'kill -TERM'. The bare metal equipment has 28 GB of RAM.

  guixbuilder01 3189 39.0 91.4  09:01 03:57
/gnu/store/ad8351jvj61da279a3ddfs2gmk3whvdq-guile-wrapper/bin/guile
--no-auto-compile
/gnu/store/py8f9r0k22hmhahyz7hm7hrbdrvfa9n2-profile/bin/guix repl -t
machine

Any pointers would be welcome. Thanks!

Kind regards
Felix

It's probably not a problem with your changes, the commit from the Guix
master branch that you based your changes on was in a bad state. That's
been fixed now so try rebasing your changes.
