功能端丢包现象:
1、联通5G带着GTP头IPv6出现丢包现象无策略、小流量情况下都丢剥离GTP头后不丢包 
*1已解决*
2、同一机房两台功能端一台丢一台不丢偶尔重启sapp可以恢复。
3、开启App Sketch插件后功能端表现出负载过大开始丢包
*1已解决***liuxueli** commented on *2022-03-08T14:18:24.195+0800*:
* 问题1调整驱动分流模式由distmode=4改成distmode=2驱动分流模式包含5种方式
** 0软件二元组哈希分流
** 1软件四元组哈希分流
** 2软件二元组哈希分流(解析到隧道内层,即内层二元组分流)
** 3软件四元组哈希分流(解析到隧道内层,即内层四元组分流)
** 4使用硬件计算结果分流

关于开启App Sketch后丢包定位下是流量、App特征还是代码实现的问题。 [~liuxueli]

问题1功能端更新到22.01版本后monit_stream开始出现丢包monit_device不丢目前驱动的分流模式已经改成distmode=2查看sapp cpu占用个别核会跑到100% [~liuxueli]

* 问题12022/03/14上午查看25.3/4设备原始流量1.5GbpsCPU使用3000%(共5200%),未发现丢包的现象。
* 下午出现丢包现象:参见{*}TSG-9956{*}
