I am trying to reindex a source index which has 500k documents with new mapping but the reindexing gets stuck at 52000 docs and doesn't proceed. It worked perfectly for another index which had 190k docs. Kindly help me with this.

```auto
   body = {
        "source": {
            "index": source_index
        },
        "dest": {
            "index": new_index
        }
    }

```

What do you mean by "get's stuck"?

By stuck, I mean it is not reindexing more documents. It looks like it stopped with 52000 docs .
