spring - 客户端发现后 Eureka Server 停止工作

Question

我的应用程序中有 Eureka 服务器和客户端。当我尝试启动客户端时，Eureka Server 停止响应并收到此日志：

下面是客户端和服务器配置：

客户端主类：

@SpringBootApplication
@EnableAutoConfiguration
@EnableDiscoveryClient
@EnableHypermediaSupport(type = EnableHypermediaSupport.HypermediaType.HAL)
@EnableFeignClients
public class NyotaPlateformApplication {

    public static void main(String[] args) {
        SpringApplication.run(NyotaPlateformApplication.class, args);
    }
}

application.properties 客户端：

server.port= ${PORT:4445}

spring.application.name= nyota-plateform
spring.main.banner-mode=off
security.oauth2.resource.user-info-uri= http://localhost:8999/user

eureka.client.serviceUrl.defaultZone= http://localhost:8761/eureka/

服务器主类：

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
    }
}

应用属性：

server.port: 8761
spring.application.name: discovery-server    
logging.level.org.springframework.cloud.netflix.eureka: TRACE           
eureka.instance.hostname: localhost
eureka.client.registerWithEureka: false
eureka.client.fetchRegistry: false
eureka.client.serviceUrl.defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

其他客户端具有相同的配置。当我只启动尤里卡服务器时，它工作正常，启动超过 1 个客户端后，它停止响应。一段时间后，我在客户端收到以下错误：

可能是什么原因？
