Hi, dear Community of elastic I got this problem trying to reindex from a remote host of my production environment to my development one in the elastic cloud

 ![Elastic%20Reindex%20Error](https://us1.discourse-cdn.com/elastic/original/3X/0/e/0e0b6d880362fc23e482bdec6f9f0bb47d32d5b1.png)

It may the error caused by the different versions of the hosts?  
I tried doing it by CURL in my terminal, same error in kibana as my console.  
The index has the same mapping settings  
I create the index prior run the code and both have the same mappings as I described above.

Production Environment: 6.3.0  
Development Environment: 6.7.0

Please don't post images of text, they're impossible to search and they cannot be read by those of us using a screenreader.

The error looks like a rejected execution exception: the write queue capacity is only 200 tasks but the reindex tried to submit a batch containing 210 items all for the same shard. You can limit the size of batches by setting the `source.size` parameter.

Thank you very much for your help David, I'm sorry that won't happen again, I'm going to edit the post, btw **I run the following command at dev tools** :

```
    POST _reindex
{
  "source": {
    "size": 1000,
    "remote": {
      "host": "https://c97a616987f58b3a2d7c1c48412d6674.us-central1.gcp.cloud.es.io:9243/",
      "username": "enyer.q",
      "password": "Eny3rQ"
    },
    "index": "social __instagram__ messi"
   
  },
  "dest": {
    "index": "social __instagram__ messi__dev"
  }
}

```

**and I got the same error:** `

It looks like you're still overflowing the write queue. There's only room in the queue for 200 tasks and you're asking for batches of 1000.
