S01072

## Error Message {#error_message .section}

`Failed to garbage collect old versioned data because the cached table information on disk could not be found. RefId: S01072`

## Probable Causes {#probable_causes .section}

During the garbage collection of multiple versions of chunks, if a data node fails to retrieve the cached table information, it will be unable to clean up the old version data. If this error continues to occur, the disk space may be gradually exhausted. To avoid this problem, it is necessary to ensure that the data node can accurately access and manage the cached information of the table.
