Briefly, this error occurs when Elasticsearch fails to delete certain blobs (binary large objects) from the system. This could be due to insufficient permissions, network issues, or the blobs being in use or locked. To resolve this issue, you can try the following: 1) Ensure that Elasticsearch has the necessary permissions to delete blobs. 2) Check your network connection and ensure it’s stable. 3) Make sure the blobs are not being used or locked by another process. 4) If the blobs are corrupted, you might need to repair or recreate them.
