[TiDB Usage Environment] Production Environment
[TiDB Version] v6.2.0
[Reproduction Path]
Both upstream and downstream TiDB versions are v6.2.0. First, use BR to back up data to the downstream, then use TiCDC for synchronization.
[Encountered Problem: Phenomenon and Impact]
After a period of synchronization, an error occurs: write error: write /dev/stderr: no space left on device
Resource usage is normal, TiCDC progress is stuck but no error is displayed.
The data directory of TiCDC uses OSS storage.
