Web 应用程序 [ROOT] 似乎已启动名为 [pollingConfigurationSource] 的线程，但未能停止它。内存泄漏

您好，我在运行项目时遇到内存泄漏错误。我在用spring boot + quards scheduler + liquibase + postgreSQL 9.6。这些是我们正在使用的技术。

Error:

12018-10-15 11:43:19.005  WARN [billing,,,] 19152 --- [ost-startStop-1] o.a.c.loader.WebappClassLoaderBase       : The web application [ROOT] appears to have started a thread named [pollingConfigurationSource] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:

我的配置代码是：

package com.xyz.api;

@Slf4j
@XyzService
@EnableWebSecurity
@EnableResourceServer
@EnableGlobalMethodSecurity( prePostEnabled = true )
public class BApplication extends ResourceServerConfigurerAdapter implements WebMvcConfigurer
{
    public static void main( String[] args )
    {
        SpringApplication.run( BApplication.class, args );
    }

    @Override
    public void configure( ResourceServerSecurityConfigurer resources )
    {
        resources.resourceId( "xxxx" );
    }

    @Override
    public void configure( HttpSecurity http ) throws Exception
    {
        http.authorizeRequests()
            .antMatchers( "/" ).permitAll()
            .antMatchers( "/docs/**" ).permitAll()
            .antMatchers( "/actuator/health" ).permitAll() // can we tighten this up?
            .anyRequest().authenticated(); //individual services use annotations
    }

    @Override
    public void addViewControllers( ViewControllerRegistry registry )
    {
        registry.addViewController( "/" ).setViewName( "forward:/docs/index.html" );
    }

    @Bean
    public Clock clock()
    {
        return Clock.systemUTC();
    }

    @Bean
    public RestTemplate restTemplate( RestTemplateBuilder builder )
    {
        return builder.build();
    }
}

实际上，这之前工作得很好，但突然在部署时出现错误。帮我解决这个问题。

我还提到：spring-cloud-starter-hystrix 和 spring-cloud-starter-archaius 集成的内存泄漏问题但没有得到任何解决方案。
