2023.5.10 16:12:00左右用户反馈，dynamic_psiphon_ip日常（或者说15:00:00查询到的IP量）是7w左右的IP量，现在只有5.4w左右，IP数量降低，且dynamic_psiphon_ip更新时间仍然一直显示是15:00：00，要求排查原因。
|
|
|
|
|
|
背景：当天用户在界面发现以前策略创建的object要求删除。

CN程序排查：
|
|
|
|
|
|
* vpn-thwarting程序每1小时调用CM的API接口向dynamic_psiphon_ip对象中推送item，但是16:12左右发现该IP Object最新更新时间是15:00，而不是预期的16:00，猜测最新一次新增失败。
|
|
|
|
|
|
* 查看程序本地日志发现最新一次（16:00:00）调用API新增IP失败，报错：Policy object configuration update failed：Internal Server Error

CM程序排查：
|
|
|
|
|
|
* 原因：根据/data/tsg-2211/cm/api/logs日志发现：16:00左右 API接收到三次请求： 界面Object删除，CN删除IPs，CN新增IPs，并发更新数据期间遇到数据库锁竞争，其中CN请求新增IPs的事务锁竞争失败回滚。
|
|
|
|
|
|
* 解决：数据库事务执行完毕后自行释放锁

现场17:00左右查询数据库锁释放，object更新恢复正常。
|
|
|
|
|
|
预计object item数量应该是在昨天晚上现场时间20:00之后恢复，2023.5.11验证该object中ip数量为72874，恢复正常
