MongoDB keeps deleted log files open after rotation

    • Type: Icon: Question Question
    • Resolution: Done
    • Priority: Icon: Major - P3 Major - P3
    • None
    • Affects Version/s: 3.6.5
    • Component/s: Logging
    • Environment:
      RHEL 7.x Linux x64, MongoDB 3.6.5 Community, Sharded Cluster

      I made a script to rotate the logs every day, but my log files remain open after the rotation (see attachment).

      Even if I restart the mongod processes, this problem will appear in the next few days.

      Is there a problem with my script? Or the "kill -SIGUSR1 <pid>" command cannot be used when MongoDB is balancing? 

      Any suggestions or root cause guessing?

      Thanks~
