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
