我们为 JBoss 应用程序服务器设置了前端 Apache Web 服务器。我们的环境是 Myfaces 1.2.6 with Tomahawk, Ricfaces 3.3.3
请注意，仅从我们的其中一个客户端网络上传失败仅适用于大文件。（有时超过 50-100MB会失败，超过 200MB总是会失败）
前端 apache Web 服务器中的日志显示：

我不确定 1. 该客户端网络中的防火墙是否会出现此问题或 2. apache / jboss 配置（请求超时等） - 但随后从其他国家网络上传作品。
只是添加一个关于 Richfaces fileupload 组件客户端行为的注释：它正在尝试多次上传同一个文件。这从进度条中可以明显看出，它尝试上传一些字节，失败，再次从头开始，再次失败......这种模式也与 apache 服务器日志匹配，如下所示。最后，经过 5-10 次尝试，上传失败并显示“发生传输错误”。

请分享我可以尝试的任何指示或解决方法，这将非常有帮助。
@update：使用调试日志运行 apache 后，错误日志显示单个大小为 200MB 的文件的上传。在这种情况下，碰巧上传了5 次尝试，在每次尝试中，错误消息都是
[client xxxx] (OS 10054)一个现有的连接被远程主机强行关闭。: core_output_filter: 将数据写入网络
，但最后上传失败。请分享在哪里解决此问题的任何想法。
