错误的序列号和错误的分片时间

[zhangping]

如图所示出现同一个序号的两个分片，第一个分片时间稍短，切分片大小为0；

[13426136199]

图片中是13:00-15:00这个时间段内出现ts为0 的各个频道及对应的序号

[13426136199]

图片中是test_11频道 出现重复274831序号，且其中一个ts为0 的情况

[13426136199]

以下是服务器106.39.160.106出现的ts片为0的具体频道及分片序号 提供文本方便查找时进行信息拷贝

整理了一下昨天请求失败的情况，分析有可能是源的问题，如表格中前三条对比是同一个频道基本相同时间出现的问题，请参考

[13426136199]

ts片出现为0的情况多出现在106服务器上

[13426136199]

刚刚升级的版本出现ts片为0的情况如下：

[13426136199]

出现时常约5s的短时间请求404

[13426136199]

106服务器上出现ts片为0情况和下载ts片超时情况，如下图（红色框内为ts片下载用时超过5s的情况，黄色框内为ts片为0）： 下图是具体ts片下载情况：

[13426136199]

120服务器上出现的请求返回404

[13426136199]

120服务器test频道出现请求404情况的log信息如下: 120服务器test_16频道，2015-11-18的log从14:03才开始写入，之前没有生成错误log信息

[13426136199]

106服务器上出现ts片为0的具体情况如下：

[13426136199]

以下是整理的各个服务器出现访问404的情况，值得注意的是106服务器上CP注入的两个频道，相对稳定性较差，log频繁写入，几分钟就会写满一个log文件

[13426136199]

另外，近期出现ts下载超时情况，频率较少，希望也关注一下：

[13426136199]

PS：只切片不转码的服务器33目前一切正常，未出现任何错误信息

105服务器凌晨出现的频道访问404情况如下：

[13426136199]

下图是最近一段时间内出现404的频道信息，请参考（以下频道ts均已录制到本地）：

[13426136199]

ts文件存在109服务器上，4号有两个时间的ts片清理空间时丢失了，其他ts片均存在

[13426136199]

频道1234_cctv、test_cctv都是CCTV1高清，组播地址一致，所以都录制在1234_cctv路径下

[zhangping]

如下图所示，对应时间的录制文件刚好偏下，初步确定为丢包所致：
