我们正在尝试实现一个http2码头客户端，该客户端与我们的远程服务器进行多路复用连接。我们的程序如下
Security.addProvider(new OpenSSLProvider());//Conscrypt for ALPN support in jdk8
SslContextFactory sslContextFactory = new SslContextFactory.Client(true);
sslContextFactory.setProvider("Conscrypt");
sslContextFactory.setProtocol("TLSv1.3");//Use TLSv1.3
HTTP2Client http2Client = new HTTP2Client();
http2Client.setConnectTimeout(5000);
http2Client.setIdleTimeout(30000);
org.eclipse.jetty.client.HttpClient http2HttpClient = new org.eclipse.jetty.client.HttpClient(new HttpClientTransportOverHTTP2(http2Client), sslContextFactory);
http2HttpClient.setConnectTimeout(5000);
http2HttpClient.setIdleTimeout(30000);
http2HttpClient.start();
http2HttpClient.addBean(sslContextFactory);
http2HttpClient.start();
org.eclipse.jetty.client.api.Request request = http2HttpClient.POST(locationurl+locationposturl);
request.header(HttpHeader.CONTENT_TYPE, "application/json");//No I18N
request.header("Pragma", "no-cache");
request.header("Custom", customheaderName);
request.header("Secure", secureHeader);
request.header("protocol", "h2");
request.content(new StringContentProvider(myXMLRequest,"utf-8"));
request.timeout(420, TimeUnit.SECONDS);
request.idleTimeout(30, TimeUnit.SECONDS);
ContentResponse response = request.send();
if (response != null && (response.getStatus() >= 200 && response.getStatus() < 400)) {
int statuscode=response.getStatus();
byte [] wbresponse = response.getContent();
}
我们使用同步调用和conscrypt（安全提供程序）在jdk8中支持ALPN并使用TLSv1.3。我们能够成功向我们的远程位置发出http2请求。但是我们面临一个问题，即大多数线程无限期地挂起，直到重新启动服务器。我们在两端都使用tomcat 9.x，每个远程服务器都位于专用的HAproxy（用作h2 / ssl终结器）的后面。
客户： 使用的安全提供程序： Conscrypt-2.1.0 ，JAVA： JDK 8 ，tomcat： 9.0.21 ，码头： 9.4.19
服务器： JAVA： JDK 11 ，tomcat： 9.0.21 ，Haproxy： 2.0
我检查了码头文档是否存在超时，我们已经配置了所有超时，但是仍然不知道为什么线程会无限期挂起。我们有相同的线程转储，

最大的问题是它不会在测试网格中发生，而只会在生产服务器中发生。
请帮助解决此问题
