Improving job status problem due to defunct process

Sometimes, defunct can occur in job processes for a variety of reasons.

For example, 29460 below is one of the processes of some job.

ps -ef | grep bg92

bg92.pa+ 29460 1 1 2022 ? 08:03:02 [Novas] <defunct>


And if a defunct process occurs, LSF does not modify job status from RUN to EXIT/DONE.

Because LSF does not check whether a process is defunct and defunct process is not killed by any OS signal (only a reboot can fix it).

So we should doubt if any job has been marked RUN for too long.

There is one problem here.

If the cluster size is small and the number of running jobs is small, we can check by job.

However, if the cluster size is large and there are a lot of running jobs, it is almost impossible for people to check whether the job process is defunct.

So I hope to check the defunct process in the LSF and remove the job.

The defunct process does not respond to any signal from the OS.
Only a reboot can solve it.
However, I think that the job of the defunct process is no need to be maintained with the RUN status.

Unnecessary RUN status result in wasted slots and multiple resources.

    As per the previous comment, removing the job just hides the fact that there is a problem with the hardware - which in turn could lead to additional failures.
    We don't think hiding this is the right approach.

    Removig the job with defunct process automatically may hide real applicatoin and/or system issues. Maybe considering using LSF watchdog feature to monitor such situation, send alert, and then take action.
