Hi, ``` I have 5 million records in database i create the index through ``` BulkRequestBuilder every 10,000 records pushing to elasticsearch But while sometimes getting _ESRejectedExecutionException_ ES\_MIN=2gb ES\_MAX=2gb cluster.name: pandy node.name: "pandy\_server" index.number\_of\_shards: 5 index.number\_of\_replicas: 1 bootstrap.mlockall: true index.store.compress.stored: true index.refresh\_interval: 1m indices.memory.index\_buffer\_size: 90% threadpool.search.type: fixed threadpool.search.size: 15 index.cache.filter.expire: 1m indices.cache.filter.size: 256mb threadpool.index.type: fixed threadpool.index.size: 25 threadpool.bulk.type: fixed threadpool.bulk.size: 60 ``` I have *only 6GB* RAM ``` -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

The bulk thread pool has a cap on the queue size which is 50 (threadpool.bulk.queue\_size). Once you reach that cap, you will start getting the rejected exceptions. That is there for a reason so that the thread pool does not get out of control. You can try to increase the queue size slightly but if that still doesn't fix your problem, then you need to reduce your bulk concurrency/size since you may be reaching the limits of what your node hardware can handle. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hi Binh, ``` Thanks for your reply.I am setting for *threadpool.bulk.queue_size: ``` 300\* in elasticsearch.yml it's okay.
