Hello list,
There exists a patch which is hanging around in our development tree for
ages now which we used to avoid zombie processes.
This is maybe related to some old stuff found here:
http://www.busybox.net/lists/busybox/2004-August/012422.html
Our inittab calls a startscript which is not ended during runtime, but
only when the settopbox shuts down.
If you are interested, here's the patch.
ppc8xx/linux-2.4.35/libc-2.3.6/gcc-3.4.6.
Best regards
Harald
