# 执行被中止，因为此状态机的总执行次数超过了并发执行配额

- **ID:** `aws/stepfunctions-execution-aborted-quota`
- **领域:** aws
- **类别:** resource_error
- **验证级别:** ai_generated
- **修复率:** 78%

## 根因

Step Functions状态机已超过其并发执行限制（标准工作流默认每个账户每个区域1000个）。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| Step Functions 2023-10-01 | active | — | — |
| AWS CLI 2.16.0 | active | — | — |

## 解决方案

1. ```
   停止不再需要的运行中执行：
# 列出运行中的执行：
aws stepfunctions list-executions --state-machine-arn arn:aws:states:us-east-1:123456789012:stateMachine:MyStateMachine --status-filter RUNNING
# 停止每个执行：
aws stepfunctions stop-execution --execution-arn arn:aws:states:us-east-1:123456789012:execution:MyStateMachine:execution-id
# 等待配额释放。
   ```
2. ```
   通过AWS支持请求增加并发执行的服务配额：

   ```
3. ```
   如果工作负载是高吞吐量和短生命周期的，使用Express工作流代替Standard：
# Express工作流具有更高的并发执行限制（每个账户每个区域100,000个）。
aws stepfunctions create-state-machine --name MyExpressStateMachine --definition '{}' --role-arn arn:aws:iam::123456789012:role/MyRole --type EXPRESS
   ```

## 无效尝试

- **Delete completed executions manually** — Completed executions do not count toward the concurrent quota; only running executions matter. (90% 失败率)
- **Increase the state machine's timeout** — Increasing timeout keeps executions running longer, potentially making the quota issue worse. (95% 失败率)
- **Restart the state machine from the beginning** — Restarting creates a new execution, which will also be blocked if the quota is still exceeded. (85% 失败率)
