我正在使用stormcrawler 1.16和elasticsearch-7.2.0。java版本是1.8.0ü。storm版本是1.2.3，maven版本是3.6.3。
我用mvn原型创建了一个项目-

mvn archetype:generate -DarchetypeGroupId=com.digitalpebble.stormcrawler - 
    DarchetypeArtifactId=storm-crawler-elasticsearch-archetype -DarchetypeVersion=LATEST

我制作了一个seeds.txt文件，并放置了9个url，仅用于测试，并在--remote模式下使用reaedme.md文件中给出的命令提交了拓扑。
它成功运行并按预期爬网页面。
但当我在seeds.txt文件中放入8000个url时，问题就出现了。
我再次运行es\u indexinit.sh文件，并使用与之前相同的命令提交拓扑。然后我得到这个错误-

然后在worker.log文件中查找错误。我在那边发现了同样的错误。然后我检查碎片的健康状况-

       }
      }
    },
      ".kibana_1" : {

    "0" : {

      "primary_active" : true,
      "active_shards" : 1,
      "relocating_shards" : 0,
      "initializing_shards" : 0,
      "unassigned_shards" : 0
            }
           }
         }
      }
    }

碎片的健康是绿色的。现在，如果我在一个不同的或新的项目中提交爬虫拓扑，拓扑仍然是理想的，并且不发射或转换任何元组。
我使用的是彼此兼容的版本吗？我应该使用Java11进行elasticsearch还是可以正常工作？
关于示例的详细信息-我正在使用ec2 medium intance Ubuntu18.04和4GB内存。
有人能解释一下问题是什么吗？
