广域网下文件传送失败的问题。
版本：anychat V4.9bug现象：局域网下文件传输没有问题。但是在广域网下，服务端：文件超过300k左右，就发现在server的temp文件夹下有临时文件，而且临时文件比原文件大，业务服务程序收不到回调，过了一段时间(几十秒)后，临时文件消失。客户端：调用QueryTransTaskInfo查询传输状态时，进度不走，速度在变。服务器是公网IP地址，有端口映射，且可能有保护ping不通，但是传输小文件是可以的，是否是因为UDP的传输，不能保证可靠达到，有什么样的措施可以解决文件传送问题吗？
您好，是否有条件测试一下，不通过端口映射的服务器，是否正常？ 只有端口映射的公网IP条件，所以，与你们demo.anychat.cn的服务器测试过，也是一样的，你们也可以测试下。 据我所知，你们的服务器好像不存在端口映射的情况，如果情况一样，那么可能你们的机制或许有点问题。 即在udp的基础上完成tcp的功能，可能还有bug，特别是网络情况不是很好的情况，如果你们的服务器在你们局域网的话，可能测试不了。 您好，请参考帖子：http://www.anychat.cn/faq/index.php?action=artikel&cat=2&id=266&artlang=zh ，打开调试模式，然后将出现问题的log帖上来我们帮您分析一下原因。 日志如下： Trans Task Status: srcUserId:1, tarUserId:0, TaskId:28913, Status:7
具体日志文件见附件。
状态为7的是什么，QueryTransTaskInfo这个接口里没有状态为7的说明。 您好，状态7为：用户已离线，是新版本增加的，可能负责文档的同事还没来得及更新上去。
请上传一下文件发起方、文件接收方两边的日志文件：BRAnyChatCore.log
