Folks-

I have been employing DU's autonice facility for a while now.
However, after upgrading to DU 4.0D, it appears that autonice
has stopped working. I checked sysconfig to make sure the
parameter is still set, and it is:

    113% sysconfig -q proc | grep auto
    autonice = 1
    autonice-time = 900
    autonice-penalty = 14

Under 4.0B, these settings reniced a process to 14 after 15 minutes.

But the nice limit is not being activated:

    114% cpups| head | cut -b 1-100
    %CPU TIME ELAPSED PSR PRI PPR NI PID LOGNAME COMMAND
    99.9 36:06.36 01:36:58 6 44 19 0 10122 mcnitt /usr/local/fbscapp/matlab5/bin/alp

( NOTE: cpups is just a C-shell alias defined as
     ps -e -o pcpu=9999%CPU,cputime,etime,psr,pri,psxpri,nice,pid,logname,command | sort -rn )

Under 4.0B, the process with PID 10122 above would have been reniced.

Has something changed in the way autonice works between 4.0B and 4.0D?

Thanks.
