I’ll deploy a fix to ‘cuirass remote-server’ in the coming days, which
should address this.

The longer story is that Ricardo noticed that the build backlog had been
growing for a couple of months (see “Pending builds”):

  https://ci.guix.gnu.org/metrics

We discussed this on guix-sysadmin and found that this was due to the
poor performance of a SQL query at the core of ‘cuirass remote-server’
that was roughly linear in the number of packages in the database.  With
help from Chris Baines, this is now fixed:

  https://git.savannah.gnu.org/cgit/guix/guix-cuirass.git/commit/?id=17338588d4862b04e9e405c1244a2ea703b50d98

I’ve been test-driving this and other changes on guix.bordeaux.inria.fr
for the last few days to get some confidence.  It was conclusive so I’ll
go ahead and deploy it on ci.guix hopefully this week-end.

Thanks,
Ludo’.
