Re: [foxboro] Defunct process?

I can answer the generic question.


A defunct process is a child process that has completed its execution and
whose parent has not executed a wait(2) call to see the exit code from the
child.


The defunct process will remain until the parent "reaps its children" - I
hate that term, but that's what its called.


On the specifics of this case, are you saying that they never go away
(abnormal) or that they take a long time to go away (probably normal).

        Here's something I noticed on many of my AW-51s (B- and D-style):

        18AW01-dmdo> ps -eaf | grep defunct
            root  1727  1721  0                   5:07 <defunct>
            dmdo 18529 18523  0 09:51:17 pts/3    0:00 grep defunct

        18AW01-dmdo> ptree 1727
        1721  /opt/fox/hstorian/bin/hist_srv
          1727  <defunct>

        So it looks like it's historian related. I can kill the defunct one,
but
        another defunct process will be there if we enter and exit the
(legacy)
        Historian Configurator. What is this defunct process and what caused
it?
        (BTW, we are still using Display Manager.)

        Thanks for any info.
