## Root Cause
During rolling deployment, execution
`97058338-052a-4528-87f4-98c88416bb7f` got stuck in QUEUED state
because:
1. Pod acquired cluster lock successfully during shutdown
2. Subsequent setup operations failed (ThreadPoolExecutor shutdown,
resource exhaustion, etc.)
3. **No error handling existed** around the critical section after lock
acquisition
4. Cluster lock remained stuck in Redis for 5 minutes (TTL timeout)
5. Other pods couldn't acquire the lock, leaving execution permanently
queued
## The Fix
### Problem: Critical Section Not Protected
The original code had no error handling for the entire critical section
after successful lock acquisition:
```python
# Original code - no error handling after lock acquired
current_owner = cluster_lock.try_acquire()
if current_owner != self.executor_id:
return # didn't get lock
# CRITICAL SECTION - any failure here leaves lock stuck
self._execution_locks[graph_exec_id] = cluster_lock # Could fail: memory
logger.info("Acquired cluster lock...") # Could fail: logging
cancel_event = threading.Event() # Could fail: resources
future = self.executor.submit(...) # Could fail: shutdown
self.active_graph_runs[...] = (future, cancel_event) # Could fail: memory
```
### Solution: Wrap Entire Critical Section
Protect ALL operations after successful lock acquisition:
```python
# Fixed code - comprehensive error handling
current_owner = cluster_lock.try_acquire()
if current_owner != self.executor_id:
return # didn't get lock
# Wrap ENTIRE critical section after successful acquisition
try:
self._execution_locks[graph_exec_id] = cluster_lock
logger.info("Acquired cluster lock...")
cancel_event = threading.Event()
future = self.executor.submit(...)
self.active_graph_runs[...] = (future, cancel_event)
except Exception as e:
# Release cluster lock before requeue
cluster_lock.release()
del self._execution_locks[graph_exec_id]
_ack_message(reject=True, requeue=True)
return
```
### Why This Comprehensive Approach Works
- **Complete protection**: Any failure in critical section → lock
released
- **Proper cleanup order**: Lock released → message requeued → another
pod can try
- **Uses existing infrastructure**: Leverages established
`_ack_message()` requeue logic
- **Handles all scenarios**: ThreadPoolExecutor shutdown, resource
exhaustion, memory issues, logging failures
## Protected Failure Scenarios
1. **Memory exhaustion**: `_execution_locks` assignment or
`active_graph_runs` assignment
2. **Resource exhaustion**: `threading.Event()` creation fails
3. **ThreadPoolExecutor shutdown**: `executor.submit()` with "cannot
schedule new futures after shutdown"
4. **Logging system failures**: `logger.info()` calls fail
5. **Any unexpected exceptions**: Network issues, disk problems, etc.
## Validation
- ✅ All existing tests pass
- ✅ Maintains exact same success path behavior
- ✅ Comprehensive error handling for all failure points
- ✅ Minimal code change with maximum protection
## Impact
- **Eliminates stuck executions** during pod lifecycle events (rolling
deployments, scaling, crashes)
- **Faster recovery**: Immediate requeue vs 5-minute Redis TTL wait
- **Higher reliability**: Handles ANY failure in the critical section
- **Production-ready**: Comprehensive solution for distributed lock
management
This prevents the exact race condition that caused execution
`97058338-052a-4528-87f4-98c88416bb7f` to be stuck for >300 seconds,
plus many other potential failure scenarios.

- Ability to make outbound HTTPS connections
Updated Setup Instructions:
We've moved to a fully maintained and regularly updated documentation site.
👉 Follow the official self-hosting guide here
This tutorial assumes you have Docker, VSCode, git and npm installed.
⚡ Quick Setup with One-Line Script (Recommended for Local Hosting)
Skip the manual steps and get started in minutes using our automatic setup script.
For macOS/Linux:
curl -fsSL https://setup.agpt.co/install.sh -o install.sh && bash install.sh
For Windows (PowerShell):
powershell -c "iwr https://setup.agpt.co/install.bat -o install.bat; ./install.bat"
This will install dependencies, configure Docker, and launch your local instance — all in one go.
🧱 AutoGPT Frontend
The AutoGPT frontend is where users interact with our powerful AI automation platform. It offers multiple ways to engage with and leverage our AI agents. This is the interface where you'll bring your AI automation ideas to life:
Agent Builder: For those who want to customize, our intuitive, low-code interface allows you to design and configure your own AI agents.
Workflow Management: Build, modify, and optimize your automation workflows with ease. You build your agent by connecting blocks, where each block performs a single action.
Deployment Controls: Manage the lifecycle of your agents, from testing to production.
Ready-to-Use Agents: Don't want to build? Simply select from our library of pre-configured agents and put them to work immediately.
Agent Interaction: Whether you've built your own or are using pre-configured agents, easily run and interact with them through our user-friendly interface.
Monitoring and Analytics: Keep track of your agents' performance and gain insights to continually improve your automation processes.
Read this guide to learn how to build your own custom blocks.
💽 AutoGPT Server
The AutoGPT Server is the powerhouse of our platform This is where your agents run. Once deployed, agents can be triggered by external sources and can operate continuously. It contains all the essential components that make AutoGPT run smoothly.
Source Code: The core logic that drives our agents and automation processes.
Infrastructure: Robust systems that ensure reliable and scalable performance.
Marketplace: A comprehensive marketplace where you can find and deploy a wide range of pre-built agents.
🐙 Example Agents
Here are two examples of what you can do with AutoGPT:
-
Generate Viral Videos from Trending Topics
- This agent reads topics on Reddit.
- It identifies trending topics.
- It then automatically creates a short-form video based on the content.
-
Identify Top Quotes from Videos for Social Media
- This agent subscribes to your YouTube channel.
- When you post a new video, it transcribes it.
- It uses AI to identify the most impactful quotes to generate a summary.
- Then, it writes a post to automatically publish to your social media.
These examples show just a glimpse of what you can achieve with AutoGPT! You can create customized workflows to build agents for any use case.

🤖 AutoGPT Classic
Below is information about the classic version of AutoGPT.
🛠️ Build your own Agent - Quickstart
🏗️ Forge
Forge your own agent! – Forge is a ready-to-go toolkit to build your own agent application. It handles most of the boilerplate code, letting you channel all your creativity into the things that set your agent apart. All tutorials are located here. Components from forge can also be used individually to speed up development and reduce boilerplate in your agent project.
🚀 Getting Started with Forge – This guide will walk you through the process of creating your own agent and using the benchmark and user interface.
📘 Learn More about Forge
🎯 Benchmark
Measure your agent's performance! The agbenchmark can be used with any agent that supports the agent protocol, and the integration with the project's CLI makes it even easier to use with AutoGPT and forge-based agents. The benchmark offers a stringent testing environment. Our framework allows for autonomous, objective performance evaluations, ensuring your agents are primed for real-world action.
