exception thrown : failed to execute pipeline for a bulk request org.elasticsearch.common.util.concurrent.EsRejectedExecutionException: rejected execution...queue capacity = 500, org.elasticsearch.common.util.concurrent.EsThreadPoolExecutor@766bbb6a[Running, pool size = 32, active threads = 32, queued tasks = 576, completed tasks = 3994308]
