Has anyone noticed that building haddocks on GitHub Actions causes an out of memory condition? It specifically seems to occur on 9.0-9.6 but not 8.8 and 8.10. Here are a couple of runs showing the behavior:
- Bump transformers · tomjaguarpaw/haskell-opaleye@c27708b · GitHub
- fixup · tomjaguarpaw/haskell-opaleye@6ac5e5d · GitHub
The error message is “Error: Process completed with exit code 143.” 143 is SIGTERM, which I expect was sent by some supervisor process on an out of memory condition.
And here’s a run where I disabled building haddocks. Everything builds fine[1]:
The specific Haddock command that I’m running is cabal v2-haddock --haddock-hoogle. I don’t expect this has anything to do with GitHub Actions specifically, it’s just that that is a low-memory environment so it will trigger an out of memory condition much more easily.
[1] But interestingly 9.0-9.6 take 7-10 minutes to build and test, whereas 8.8 and 8.10 take 2-3 minutes.
