I don't know about perl, but I am *guessing* that would work. An early solution (circa 1997/8) was to use a little program written in C to do the same thing. I've have to search my records or the list archive to dig that out.

But it begs the question, why not just use PHANTOM? Are you assuming some doubling of processes or overhead that really isn't there? I'm not understanding why you would think hammering the process grp id is preferable to letting PHANTOM take care of it for you.

Maybe I'm missing a nuance here.

Hi Cliff,

Can I also simply wrap the UV process in something that changes the
pgid? (e.g.: the setpgrp command in perl)

That is the reason for having the cron script use the PHANTOM command.

I'm not sure, but wasn't there some discussion a while back stating that multiple UV processes initiated via cron would be fine if each process had their own unique process group id (not just a unique process id)?
