Last updated: 2026-03-17
Forgeon limits concurrent builds per tenant to keep queues fair and fast.
What happens when you hit the limit
- New builds queue automatically
- You can cancel older builds to free capacity
When to increase limits
- Multi‑service apps
- Monorepos with frequent changes
- Teams with heavy CI usage
Build queue hygiene
- Cancel outdated builds from superseded commits.
- Prioritize production/staging branches during incidents.
- Avoid triggering multiple redundant builds for the same SHA.
Troubleshooting
Build won’t start
- Check the build queue
- Cancel older builds or request a higher limit
