功能端地址：
192.168.21.3-4
192.168.22.1-2
大概几十分钟重启一次**liuxueli** commented on *2022-12-03T10:49:44.387+0800*:
* 根据重启生成的coredump分析，内存已经写乱，怀疑插件存在写越界的情况
** 2022-12-02 21:00:00   192.168.21.3-4，192.168.22.2关闭dtls解析层及业务层后，程序连续运行13小时未重启，{color:#FF0000}初步定位dtls相关插件存在写越界{color}
*** fw_dtls_plug-1.0.1.5f7daf5-1.el7.x86_64
*** dtls-1.0.4.cfc47d7-1.x86_64

* 192.168.21.4在运行15小时后出现重启，已定位为基础协议识别插件导致，参见：TSG-12915 
---
**liuxueli** commented on *2022-12-04T14:26:04.280+0800*:
* 192.168.21.3出现一次重启，已定位为HTTP协议解析层插件url decode函数导致，参见：TSG-12926

**liuxueli** commented on *2022-12-05T17:29:40.461+0800*:
* 2022-12-05 HTTP解析层与app_proto_identify(基础协议识别)插件非法访问导致重启的问题已修复。

**liuxueli** commented on *2022-12-05T17:35:12.339+0800*:
* 192.168.21.3/4 使用从应用模式，运行sapp+dtls解析层，发现程序重启频繁，[~pengxuanzheng] 可以使用从应用进行调试
** 生成的minidump目录：
*** /run/sapp/crashreport/ 
** 从应用目录
*** ：/opt/tsg/sapp_slave/;
** 从应用启动方式 
*** ./r2; 后台会运行sapp_slave和r3；ps xaf可以看到
** 从应用停止方式
*** killall r3 sapp_slave
** 重启记录：

http与app_proto_identify更新之后，打开dtls和fw_dtls_plug，没有出现重启现象，已经正常运行五个小时，后续继续观察

[~pengxuanzheng] 补充下详细信息，192.168.21.3-4和192.168.22.1-2全部打开都没有出现重启？正常运行五个小时是从什么时刻到什么时刻？

**pengxuanzheng** commented on *2022-12-07T17:12:04.116+0800*:
昨天中午12点多到傍晚17点多正常运行，今天21.3和21.4 有重启，分析代码发现，tsg_master使用dtls_parse_sni的时候，如果此时是server_hello，可能会因为解析到错误的字节数导致发生非法读写。修改代码后，更新到21.3, 21.4，22.1和22.2，观察 SAPP是否还会发生重启现象。TSG-12987
