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
