我们有一个运行Infinispan 13.0.12高速缓存的Spring-Boot REST应用程序，我们看到了周期性的、看似随机的应用程序无响应的情况。线程转储表明有超过200个线程处于这种状态：

我们的Java配置如下所示：

@Autowired
@Bean
public SpringEmbeddedCacheManagerFactoryBean springEmbeddedCacheManagerFactoryBean(GlobalConfigurationBuilder gcb, ConfigurationBuilder configurationBuilder) {
    SpringEmbeddedCacheManagerFactoryBean springEmbeddedCacheManagerFactoryBean = new SpringEmbeddedCacheManagerFactoryBean();
    springEmbeddedCacheManagerFactoryBean.addCustomGlobalConfiguration(gcb);
    springEmbeddedCacheManagerFactoryBean.addCustomCacheConfiguration(configurationBuilder);
    return springEmbeddedCacheManagerFactoryBean;
}

@Autowired
@Bean
public EmbeddedCacheManager defaultCacheManager(SpringEmbeddedCacheManager springEmbeddedCacheManager) throws Exception {
    return springEmbeddedCacheManager.getNativeCacheManager();
}

@Bean
public GlobalConfigurationBuilder globalConfigurationBuilder() {
    GlobalConfigurationBuilder result = GlobalConfigurationBuilder.defaultClusteredBuilder();
    
    result.transport().addProperty("configurationFile", jgroupsConfigFile);
    
    result.cacheManagerName(IDENTITY_CACHE);
    result.defaultCacheName(IDENTITY_CACHE + "-default");

    result.serialization()
            .marshaller(new JavaSerializationMarshaller())
            .allowList()
            .addClasses(
                    LinkedMultiValueMap.class, 
                    String.class
                );
    
    result.globalState().enable().persistentLocation(DATA_DIR);
                
    return result;      
}

@Bean
public ConfigurationBuilder configurationBuilder() {
    ConfigurationBuilder result = new ConfigurationBuilder();
        result.clustering().cacheMode(CacheMode.REPL_SYNC);
        return result;
}

@Bean
public org.infinispan.configuration.cache.Configuration cacheConfiguration() {
    ConfigurationBuilder builder = new ConfigurationBuilder();

    return builder
            .clustering()
                .cacheMode(CacheMode.REPL_SYNC)
                .remoteTimeout(replicationTimeoutSeconds, TimeUnit.SECONDS)
                .stateTransfer().timeout(stateTransferTimeoutMinutes, TimeUnit.MINUTES)
            
            .persistence()
                .addSoftIndexFileStore()
                .shared(false)
                .fetchPersistentState(true)

            .expiration().lifespan(expirationHours, TimeUnit.HOURS)
            
            .build();
}

@Autowired
@Bean
public Cache<String, MultiValueMap<String, String>> identityCache(EmbeddedCacheManager manager, org.infinispan.configuration.cache.Configuration cacheConfiguration) throws IOException {
    Cache<String, MultiValueMap<String, String>> result = manager
            .administration().withFlags(CacheContainerAdmin.AdminFlag.VOLATILE)
            .getOrCreateCache(IDENTITY_CACHE, cacheConfiguration);
    result.getAdvancedCache().getStats().setStatisticsEnabled(true);
    return result;
}

并且我们使用default-jgroups-udp.xml配置运行一个三节点集群。有人能提出一个可能的原因吗？也许配置不是最佳的？
