wodingyang opened a new issue, #7468:
URL: https://github.com/apache/apisix/issues/7468

   ### Current Behavior
   
   测试环境中开启log-rotate插件，配置如下：
   plugin_attr:
     log-rotate:
       interval: 21600    # rotate interval (unit: second)
       max_kept: 20     # max number of log files will be kept
       enable_compression: false    # enable log file compression(gzip) or not, 
default false
   观察几天后发现丢失了一份文件，如下：

   猜测是否与实例重启有关，查看重启时间为15点19分，但丢失的文件应该是14点的，再查看其他机器实例，如下：

   同样是15点19分重启过的但是没有丢失文件。
   该问题是在交流群中有人反馈出现丢失文件问题后，我在自己的测试环境持续测试中发现的
   
   ### Expected Behavior
   
   _No response_
   
   ### Error Logs

   ### Steps to Reproduce
   
   1.启动apisix实例并开启log-rotate插件，每6小时切割生成一份日志文件，最多保存20份
   2.启动测试程序，每分钟执行一定的调用，观察access.log文件可以正确记录日志
   3.持续观察每日切割的文件
