CircleCI: Too long with no output (exceeded 10m0s): context deadline exceeded
A CircleCI step printed nothing for 10 minutes, so CircleCI assumed it hung and cancelled it.
Too long with no output (exceeded 10m0s): context deadline exceededToo long with no outputexceeded 10m0s context deadline exceeded CircleCI Meaning
The default no_output_timeout is 10 minutes. Long silent commands (big test suites, deployments, builds) need either periodic output or a larger no_output_timeout. If the step is truly stuck, fix the hang rather than raising the limit.
Common causes
- Long-running command with no logs
- Hung process waiting for input or a lock
- Slow network step (download, deploy)
- Tests running in silent mode
- Resource class too small, so the step crawls
⚡ Quick fix
- Set
no_output_timeout: 30mon the step - Print progress (verbose flag,
while sleep 60; do echo .; done &) - Use a larger resource class or split the work
Detailed fix by platform
CircleCI
- Add to the step:
no_output_timeout: 30m
Code examples
Longer silent timeout
- run:
name: Integration tests
command: ./run-integration.sh
no_output_timeout: 30mHow to diagnose
- Silence — What step produced no output?
- Hang — Genuinely stuck?
- Resources — Resource class sufficient?
