# CircleCI Job Timeout

Introduction

This article covers troubleshooting steps and solutions for CircleCI Job Timeout. The error typically occurs in production environments and can cause service disruptions if not addressed promptly.

Symptoms

Common error messages include:

bash

Job exceeded max execution time of 10 minutes

bash

Step timed out after 5 minutes

bash

Command did not complete within the timeout period

Common Causes

Configuration misconfiguration
Missing or incorrect credentials
Network connectivity issues
Version compatibility problems
Resource exhaustion or limits
Permission or access denied

Step-by-Step Fix

Common Error Patterns

CircleCI timeout errors typically show:

bash

Job exceeded max execution time of 10 minutes

bash

Step timed out after 5 minutes

bash

Command did not complete within the timeout period

bash

Build exceeded maximum time limit

Root Causes and Solutions

1. Default Timeout Limits

Job exceeds the default 10-minute limit.

Solution:

Increase job timeout in config:

```yaml # .circleci/config.yml version: 2.1

jobs: build: max_build_duration_minutes: 30 # Increase timeout docker: - image: circleci/node:18 steps: - checkout - run: npm install - run: npm build ```

For specific steps:

yaml

steps:
  - run:
      name: Long running step
      command: ./long-process.sh
      no_output_timeout: 20m  # Step-specific timeout

2. Insufficient Resource Class

Job runs on small resource class, causing slow execution.

Solution:

Upgrade to larger resource class:

```yaml jobs: build: docker: - image: circleci/node:18 resource_class: large # Upgrade from medium

# Available resource classes: # small (1 CPU, 2GB RAM) # medium (2 CPU, 4GB RAM) # medium+ (3 CPU, 6GB RAM) # large (4 CPU, 8GB RAM) # xlarge (8 CPU, 16GB RAM) # 2xlarge (12 CPU, 32GB RAM) ```

Or use resource class orbs:

```yaml orbs: resource-class: circleci/resource-class@1.0.0

jobs: build: resource_class: large ```

3. Slow Dependencies Installation

Dependencies download and install slowly.

Solution:

Enable caching:

```yaml steps: - restore_cache: keys: - node-deps-v1-{{ checksum "package-lock.json" }} - node-deps-v1-

run:
name: Install dependencies
command: npm ci

save_cache:
key: node-deps-v1-{{ checksum "package-lock.json" }}
paths:
- ~/.npm
- node_modules
`

For multiple dependency sources:

```yaml steps: - restore_cache: keys: - deps-v1-{{ checksum "package-lock.json" }}-{{ checksum "yarn.lock" }}

run: npm ci
- run: pip install -r requirements.txt

save_cache:
key: deps-v1-{{ checksum "package-lock.json" }}-{{ checksum "yarn.lock" }}
paths:
- ~/.npm
- node_modules
- ~/.cache/pip
`

4. No Parallel Execution

Tests run sequentially instead of in parallel.

Solution:

Enable parallelism:

```yaml jobs: test: docker: - image: circleci/node:18 parallelism: 4 # Split across 4 containers

steps: - checkout - run: npm install

run:
name: Run tests in parallel
command: |
TESTS=$(circleci tests glob "test/**/*.test.js")
TESTS=$(circleci tests split --split-by file_size --total $CIRCLE_NODE_TOTAL $TESTS)
npm test $TESTS
`

Using CircleCI test splitting:

```yaml steps: - run: name: Parallel tests command: | # Automatic splitting circleci tests glob "spec/**/*_spec.rb" | circleci tests split

# Split by timing circleci tests glob "test/**/*.test.js" | \ circleci tests split --split-by timings --timings-type classname ```

5. Large Checkout Time

Repository checkout takes too long.

Solution:

Limit checkout depth:

yaml

steps:
  - checkout:
      depth: 1  # Shallow clone, faster checkout

For specific branches:

yaml

steps:
  - run:
      name: Fast checkout
      command: |
        git clone --depth 1 --branch $CIRCLE_BRANCH \
          https://github.com/org/repo.git .

6. Docker Build Timeout

Docker image build exceeds timeout.

Solution:

Use pre-built images:

```yaml jobs: build: docker: - image: my-org/my-app:latest # Use cached image

steps: - run: docker push my-org/my-app:$CIRCLE_SHA1 ```

Or optimize Docker build:

yaml

steps:
  - run:
      name: Build Docker image
      command: |
        docker build \
          --build-arg BUILDKIT_INLINE_CACHE=1 \
          --cache-from my-org/my-app:latest \
          -t my-org/my-app:$CIRCLE_SHA1 .
      no_output_timeout: 30m

7. Waiting for External Services

Job waits for slow external services.

Solution:

Use proper retry patterns:

yaml

steps:
  - run:
      name: Wait for service
      command: |
        until curl -s http://service:8080/health > /dev/null; do
          echo "Waiting for service..."
          sleep 5
        done
      no_output_timeout: 5m

Use CircleCI wait-on orb:

```yaml orbs: wait: circleci/wait-on@1.0.0

steps: - wait/on: endpoint: http://localhost:8080/health timeout: 60 ```

8. Workflow Step Timeout

Entire workflow exceeds time limit.

Solution:

Set workflow timeout:

```yaml workflows: version: 2 build-and-test: jobs: - build - test: requires: - build

workflows: build-and-test: max_build_duration_minutes: 60 # Workflow-level timeout jobs: - build - test ```

Resource Optimization

Compare Resource Classes

```yaml # Performance comparison jobs jobs: test-small: resource_class: small steps: [run: npm test]

test-large: resource_class: large steps: [run: npm test] ```

Use GPU for ML Jobs

yaml

jobs:
  train-model:
    docker:
      - image: circleci/python:3.9-gpu
    resource_class: gpu.nvidia.medium
    steps:
      - run: python train.py

Debugging Commands

```bash # View job details curl -s https://circleci.com/api/v2/project/gh/org/repo/job/:job-id \ --header "Circle-Token: $TOKEN"

# Get job output curl -s https://circleci.com/api/v1.1/project/gh/org/repo/:build-num/output \ --header "Circle-Token: $TOKEN"

# Cancel job curl -X POST https://circleci.com/api/v2/project/gh/org/repo/job/:job-id/cancel \ --header "Circle-Token: $TOKEN" ```

Timeout Quick Reference

Timeout Type	Default	Config Key
Job execution	10 min	`max_build_duration_minutes`
Step no output	10 min	`no_output_timeout`
SSH session	10 min	SSH timeout in settings
Workflow	60 min	Workflow-level config

Optimization Checklist

Optimization	Benefit
Caching	2-5x faster deps install
Parallelism	Split tests across containers
Larger resource	Faster execution
Shallow checkout	Faster repo clone
Pre-built images	Skip Docker build

Prevention

1.Monitor job duration with insights
2.Use appropriate resource class for job type
3.Enable caching for all dependencies
4.Split tests across parallel containers
5.Set appropriate timeouts per step
6.Use Docker layer caching
