Java 卡夫卡服务自动关闭

目前我正在使用kafka_2.12-2.5.0和Java服务（Spring boot）。 我曾经先启动zookeeper kafka，然后再启动debezium服务，它们曾经成功运行。 之后，如果我尝试运行java服务，那么kafka服务将在一段时间内停止 当时Debezium连续显示这些日志：

[2020-10-09 06:45:58,503] WARN [Producer clientId=connector-producer-sql-server-connection-0] Connection to node 0 (vsi-kafka-dev-01.c.presence-ss.internal/10.128.15.238:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient:762)

[2020-10-09 11:11:39.635 [org.springframework.kafka.KafkaListenerEndpointContainer#9-0-C-1] WARN  org.apache.kafka.clients.NetworkClient - [Consumer clientId=consumer-4, groupId=vsiconsumers] Connection to node 0 (vsi-kafka-dev-01.c.presence-ss.internal/10.128.15.238:9092) could not be established. Broker may not be available.

同时Java服务不断显示这些日志：

[2020-10-09 06:45:58,503] WARN [Producer clientId=connector-producer-sql-server-connection-0] Connection to node 0 (vsi-kafka-dev-01.c.presence-ss.internal/10.128.15.238:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient:762)

我在sh文件中使用了默认属性，只是更改了DB和IP相关的更改。

您所说的“kafka服务正在停止”是什么意思？卡夫卡的经纪人真的关门了吗？还是不接受连接？还是别的什么毛病？您是否有来自Kafka或ZK进程的日志来帮助理解问题？当您运行应用程序时，请检查堆内存。如果这还不够，卡夫卡可能会倒下
