Later, I found the cause. It was due to frequent data modifications in the upstream database, possibly because the DM buffer was insufficient. It has been fixed now.

The status is normal, but the binlog drift point is not keeping up with the upstream. This was caused by frequent data modifications upstream and has been fixed.

You can see frequent delete and insert statements being logged in the dm-worker.log file.
