Datastax 4.8搜索节点--cqlsh连接错误

我最近安装在三节点集群DSE 4.8.9上 . 集群运行良好， Health . 我们已经开始从1400万中删除400万条记录，因此创建了一些墓碑 . 重新启动其中一个节点（10.0.106.7）后，该节点不再显示端口9042，因此无法通过cqlsh进行连接 . 端口7199暴露在外 .

机器设置：150 GB数据驱动器，单独光盘上10 GB提交日志，32 GB RAM，8个内核

• cassandra.yaml：listen_和rpc_address设置为相同的IP .

• cassandra-en.sh：HEAP设置为22 GB（机器有32 GB RAM）

我在system.log中观察到相当高的GC活动 . 你可以在pastebin上看到system.log

这似乎导致c *不再暴露端口9042 .

我试图让机器在这种状态下运行几个小时 . 系统日志保持活动状态，但cqlsh无法连接 . 我收到了

连接错误：（'无法连接到任何服务器'，{'10 .0.106.7'：错误（111，“尝试连接到[（'10 .0.106.7'，9042）] . 上次错误：连接被拒绝”）}）

从同一主机连接到cqlsh时 .

这导致了问题，opscenter无法连接到此实例 .

有什么建议我可以做什么来将cqlsh带回这个节点？

更新：nodetool状态的输出：

UPDATE2：

netstat -an | grep 9042从output.log中不返回任何摘录
