我从RESTEasy服务器收到一个奇怪的异常。当将特别大的响应返回给客户端时会发生这种情况。
在我的代码将结果对象返回到RESTEasy之后发生异常，因此它都在RESTEasy层内。服务器是TomCat。
小响应很好，但大响应会触发错误。如果我返回JSON或XML，并且由响应的大小触发，而不是我返回的对象中的内容，则会发生这种情况。
我已经四处寻找，但还没有找到任何有用的东西，而且此时我几乎迷失了......

更新：我实际上又发生了这种情况！ Scott的回答涵盖了第一种情况，但第二次是由于为响应头插入了一个空值。 RESTEasy在我插入它时接受了null标头值，但是当它从我的代码退出后尝试序列化响应时爆炸了。

好的，现在经历了几次 - 如果您使用前端反向代理，当我遇到问题时，我个人已经看到了这种行为。例如，我在使用nginx时遇到了问题，其中部署了系统并与不同的用户一起运行。临时目录上的权限问题意味着在响应达到特定大小之前，您可能看不到问题。例如（它是一行，换行是为了可见性）：
2017-04-20T17:46:40.03987 [nginx] 2017/04/20 13:46:40 [crit] 64537#0:

failed (13: Permission denied) while reading upstream, client: 10.0.0.1,

似乎客户端在响应完全发送到它之前关闭连接，是否可以增加客户端超时然后检查
