Hi Folks,

I have a bit of an emergency on my hands, and was hoping that someone
could give me a quick fix for avoiding zombies from a CGI script on
BSDI. 

I just need a band aid until I can find the source of the problem. I have 
way too many processes that are apparently not exiting, and I know
the guilty script ( though I don't know why it is raising hell ).
The server admin has killed them manually it appears, but I have to
stop this from happening again before they shoot me! 

Any help would be greatly appreciated on this.

Here is where I am heading now:
=================
Question:
How do I avoid zombies on a Unix system?

    Use the reaper code from the section on "Signals" in the perlipc
    manpage to call wait() when a SIGCHLD is received, or else use the
    double-fork technique described in the "fork" entry in the perlfunc
    manpage.
=================

Thanks,
Barry
