Hello Maxime,
Thanks for the report. There are 300 postgresql connection slots on berlin which is enough under nominal CI activity. However, this issue: http://issues.guix.gnu.org/53463 causes most of the Guix jobset evaluations to hang, hence the connection slots starvation. Now the 53463 issue is probably caused by two underlying issues: - Offloading is never timing out - Guix on aarch64 can not be evaluated correctly. Many things to fix then. Mathieu
