### 更大的错误 - 崩溃 { #bigger-errors-crashes }

尽管如此，在某些情况下，我们编写的一些代码可能会导致整个应用程序崩溃，从而导致 Uvicorn 和 Python 崩溃。 💥

尽管如此，您可能不希望应用程序因为某个地方出现错误而保持死机状态，您可能希望它**继续运行**，至少对于未破坏的*路径操作*。

### 崩溃后重新启动 { #restart-after-crash }

但在那些严重错误导致正在运行的**进程**崩溃的情况下，您需要一个外部组件来负责**重新启动**进程，至少尝试几次...

/// tip | 提示

...尽管如果整个应用程序只是**立即崩溃**，那么永远重新启动它可能没有意义。 但在这些情况下，您可能会在开发过程中注意到它，或者至少在部署后立即注意到它。

### Reiniciar após falha { #restart-after-crash }

Mas nos casos com erros realmente graves que travam o **processo** em execução, você vai querer um componente externo que seja responsável por **reiniciar** o processo, pelo menos algumas vezes...
