java线程已经开始阻塞实现ClientHttpRequestInterceptor的post

Question

已经实现了一个请求拦截器，该拦截器将auth头添加到输出请求并执行，但似乎在添加该拦截器后，我的服务在30分钟左右开始提供504s newrelic，我可以看到活动线程接近200个，创建资源紧缩和o获取线程转储，我可以看到所有线程都被卡住了。 拦截器内部

ClientHttpResponse response = clientHttpRequestExecution.execute(httpRequest, body);

我仔细阅读了这篇文章，认为连接池可能已经耗尽，因为默认池大小是每台主机5个，因此我将其添加到最大100个，每台主机50个，以确保此池不会在其他客户端调用中共享。这确实有助于解决一些问题，但大约90分钟后，开始出现相同的问题。这让它成为一颗滴答作响的定时炸弹

   @SneakyThrows
    @Override
    public ClientHttpResponse intercept(HttpRequest httpRequest, byte[] body, ClientHttpRequestExecution clientHttpRequestExecution) {

            httpRequest.getHeaders().put("Authorization", Collections.singletonList(String.format(TOKEN_FORMAT, getAuthorizationToken())));
            
            httpRequest.getHeaders().add(header1);
            httpRequest.getHeaders().add(AUTHENTICATION_META_HEADER, header2);
            
            ClientHttpResponse response = clientHttpRequestExecution.execute(httpRequest, body);
            
            
            if (response.getStatusCode() == HttpStatus.UNAUTHORIZED && response.getHeaders().get(AUTHENTICATE_HEADER).stream().anyMatch(parameter -> parameter.contains(TOKEN_EXPIRED))) {
                
                httpRequest.getHeaders().put("Authorization", Collections.singletonList(String.format(TOKEN_FORMAT, refreshAuthorizationToken())));
                
                response = clientHttpRequestExecution.execute(httpRequest, body);
            }
            if (response.getStatusCode() == HttpStatus.UNAUTHORIZED || response.getStatusCode() == HttpStatus.FORBIDDEN) {
                Profiler.increment("authorization_failed");
            }
            return response;
        
    }

    <bean id="outboundPoolingHttpClientConnManager" class="org.apache.http.impl.conn.PoolingHttpClientConnectionManager">
        <property name="maxTotal" value="100"/>
        <property name="defaultMaxPerRoute" value="50"/>
    </bean>

    <bean id="outboundHttpClientBuilder" class="org.apache.http.impl.client.HttpClientBuilder" factory-method="create">
        <property name="connectionManager" ref="outboundPoolingHttpClientConnManager"/>
    </bean>

    <bean id="outboundHttpClient" factory-bean="outboundHttpClientBuilder" factory-method="build"/>

我是否遗漏了一些导致资源短缺的因素，或者仅仅是我需要根据我的流量需求配置非常高的值 目前，我在这里将池大小定义为

<property name="maxTotal" value="100"/>
<property name="defaultMaxPerRoute" value="50"/>

或者在同一个请求上有多个拦截器不是一个好的做法吗

考虑到令牌只有在我们得到401时才会刷新，甚至那个调用也需要5-10毫秒，所以这不会造成瓶颈
