Can you conform with "ps axl"?

Yup, my zombie's parent PPID==1
That is really weird. init should always be reaping zombie processes, so
that having a zombie process with init as the parent, and the process
staying around would indicate some serious bug in either the kernel, or
in init.
If init is really its parent, check its "ps axl" output and
check its WCHAN. If it isn't "wait", maybe run "ktruss -p 1" to
get an idea of what it is doing instead of wait*() calls.
See ps output above; init's WCHAN==wait
So no clue on why it's not getting around to reaping child 27237.
Looks like a bug somewhere.
