我有一个 datanoise action-webservice 实现的 SOAP rails webservice，它通过将 XML SOAP 请求发布到第三方 URL 来与另一个 SOAP webservice 交互：

open("http://localhost:8080/generateResponse?xmlRequest="+CGI.escape(soapRQ.result(binding).gsub("\n","")))

这会定期导致异常（下面的堆栈跟踪）。我只是不明白是什么触发了这个 ECONNRESET：

服务器端位于 RHEL5 主机上。Rails 2.3.5 和 Ruby 1.8.7。第三部分是部署到 JBOSS 4.3 中的简单 java 战争

我发现问题是因为从 xmlRequest 参数的 ERB 绑定结果生成的 URL 的大小 - 对于使用 open 的 URL 来说显然太长了。我切换到 POST 并且工作正常。
