Thanks, Wensong, for taking time answering this question.
I do appreciate it very much.  The algorithm has been
changed to round-robin now, it does work better, but it
still has problem on the micro scale.  I will take a look
ntpdate source code to figure out if there is anything could
be the cause.  That utility is a big animal itself.

If the director CPU was under power, would that cause
this kind of problem?
