我从2.2转到5.2.2。我一直在运行一些测试，并且遇到了两个错误（一个来自记录器，另一个来自ES）
记录器：

ES（我认为这与第一个错误无关，但仍然存在）：
[WARN ][o.e.m.j.JvmGcMonitorService] [PnpfiI6] [gc][9162] overhead, spent [1.1s] collecting in the last [1.6s]
将Jest正确设置为一次调用一次的单例：
factory.setHttpClientConfig(new HttpClientConfig.Builder(elasticHost).defaultSchemeForDiscoveredNodes("https").multiThreaded(true)
.readTimeout(180000).build());
我尝试切换设置，打开和关闭multiThreaded，添加和提升readTimeout甚至connTimeout（虽然对于生产来说这似乎是一个错误）。
我认为特别大的文档可能导致超时，但我们在2.2中没有遇到这个问题。它类似于
上的公开问题Jest的github：
https://github.com/searchbox-io/Jest/issues/396
有关如何解决此问题的任何想法？为什么这个错误没有出现在2.2？
