RESTEasy异常: RESTEASY003770:响应已提交，无法处理异常

Question

我从我的RESTEasy服务器得到了一个奇怪的异常。当向客户端返回一个特别大的响应时，就会发生这种情况。

异常发生在我的代码将结果对象返回给RESTEasy之后，所以它都在RESTEasy层中。服务器是TomCat。

小的响应很好，但是大的响应会触发错误。如果我返回JSON或XML，并且是由响应的大小触发的，而不是我返回的对象中的内容，就会发生这种情况。

我到处找过了，但还没有发现任何有用的东西，现在我几乎迷失了方向.

更新:我真的让这种情况再次发生！Scott下面的回答涵盖了第一种情况，但是第二次是因为为响应头插入了一个空值。当我插入空头值时，RESTEasy接受了它，但是在退出我的代码后，当它试图序列化响应时，它失败了。

好的，现在已经经历过几次了--如果您使用的是前端反向代理，当您遇到问题时，我个人已经看到了这种行为。例如，在使用nginx部署系统并与不同用户一起运行时，我看到了一些问题。临时目录上的权限问题意味着在响应达到一定大小之前可能不会看到该问题。例如(它是一行，行间隔是表示可见性)：

2017-04-20T17:46:40.03987 [nginx] 2017/04/20 13:46:40 [crit] 64537#0: 
  *14195 open() "/usr/local/var/run/nginx/proxy_temp/6/43/0000000436" 
  failed (13: Permission denied) while reading upstream, client: 10.0.0.1, 
  server: foo.bar.com, request: "GET /this/awesome/endpoint HTTP/1.1", 
  upstream: "http://127.0.0.1:9999/this/awesome/endpoint", host: "foo.bar.com"

在响应完全发送给它之前，客户端似乎正在关闭连接，您能增加客户端超时，然后检查吗？
