MX240 FPC keeps showing "fps IPC socket is closed" logs

  • 1.  MX240 FPC keeps showing "fps IPC socket is closed" logs

    Posted 12 days ago
    Hello all?

    One of  FPCs of MX240 restarted recently after some BGP tracking with traceoptions. After that restart following log keeps appearing in log messages and management interface ip address has packet loss during that log appear time. It seems service traffic has no problem. CPU, memory, traffic volume has no change. Is anyone was experiencing this kind of situation?
