S00005

## Error Message {#error_message .section}

`Cannot accept new task <xxx> during a graceful shutdown of the server. RefId: S00005`

## Probable Causes {#probable_causes .section}

If you encounter this error, it means the server is currently in a graceful shutdown phase.

When you shut down a DolphinDB node using `kill -15` from the Web cluster manager or a terminal, the server enters a graceful shutdown phase. During this phase, the server does not accept new tasks or requests, ensuring that data and metadata of the database are securely flushed to disk.

## Solutions {#solutions .section}

Expected Behavior. Avoid submitting new tasks or requests during a graceful shutdown phase.
