Reindex is failing slice option

Elastic Stack Elasticsearch
1

We have an index with 28 shards. Reindex is failing when we use the slice option as below.

POST https://localhost:9200/_reindex?wait_for_completion=false&slices=10
{"source":{ "index": "OldIndex"},"dest":{ "index": "newIndex" }}

Error:
Under failures, we see a lot of errors as below

     {
        "shard" : -1,
        "reason" : {
          "type" : "search_context_missing_exception",
          "reason" : "No search context found for id [362565]"
        }
      },

Out of 2294306 docs, 2293280 docs reindexed and around 1026 docs missing.

Things tried and still not working

  • Slice set to 10 , 5, 4
  • added size option and set to 100
