We are not saving a pending job's task distribution, so after restarting

    slurmctld select/cons_res was over-allocating resources based upon an 
    uninitialized distribution value. Since we can't save the value without 
    changing the state save file format, we'll just set it to the default 
    value for now. This will result in an incorrect task distribution for 
    jobs that had a task distribution that was not the default and were 
    pending when the slurmctld daemon restarted, but at least resources
    will not be over-allocated.
