Weblogic 不会关闭文件（但会关闭连接）

亲爱的，

我们遇到了“打开的文件太多”的问题。

我们已经取得了一些进展，但问题仍然存在......

我们在 aix 上的 weblogic 上使用 cxf。

相关的 cxf 配置：

<http-conf:conduit name="*.http-conduit">
    <http-conf:client Connection="close" />
</http-conf:conduit>

执行此代码时：

        for(int i=0;i<1300;i++){
            response = callService(request).call();
        }

（我们不打算在生产中使用此代码，但它是为了解决问题）

-> 第一次运行成功；

-> 第二次运行暴露了问题

输出：

   netstat| wc -l

首先表明有太多的套接字仍然打开（因此 cxf 配置更改）

现在打开的套接字保持稳定 +- 400 行，在配置更改之前 >1000

但...

lsof 2> /dev/null|grep TCP|wc -l

暴露了我们目前遇到的问题

打开的套接字的数量是稳定的（所以套接字被关闭）但打开的文件的数量不是......

从托管服务器启动后的 319 到引发以下异常时的 +-1688：

如果要提供更多信息，请询问，

非常感谢您对解决此问题的任何帮助，

重新启动托管服务器“解决”了问题，但这不是生产中的选项......

TIME_WAIT 设置为 1（15 秒），所以没有解决方案......
