On my project, the duration of the GitHub Actions CI build suddenly went up from 2 minutes to 1 hours. The relevant commit at which the build time increased contained only a readme change (no code changes, no config changes, no test changes). Since then, the duration of the build is consistently 1–3 hours for every commit. I reverted to the last commit which was built under 2 minutes and pushed it, and that very same commit now was built in 2 hours.
- Do you have any suggestions where to start troubleshooting?
- Does GitHub Actions have any throttling in place besides the ones the documentation mentions?
- Can I somehow “restart” the build machine?
Thank you for your help.
