Hello Maxim,
Thanks for the report, the root cause here is the evaluation
hanging. The Postgres slots starvation is just a symptom caused by
having many concurrent (stuck) evaluation processes using slots.
I noticed this error: https://ci.guix.gnu.org/eval/320682/log/raw.
The following lines can be caused by having a multi-threaded program:
(cuirass scripts evaluate) because of its par-for-each procedure, call
"primitive-fork" in open-bidirectional-pipe of (guix inferior).
--8<---------------cut here---------------start------------->8---
warning: call to primitive-fork while multiple threads are running;
further behavior unspecified. See "Processes" in the
manual, for more information.
--8<---------------cut here---------------end--------------->8---
Not sure that it could cause the observed hang, Ludo what do you think?
Thanks,
Mathieu
