Jon,
Thanks for the reply. Yes, ignore_abort is defaulting to off, as stated
in my other post. We have a Firebox III 1000 firewall on our external,
however this does not have any features like this. I will look into
iptables.
Thanks,
Ryan

Thanks for the reply. I can't seem to find ignore_user_abort in my
php.ini. I would like to do it at server level, rather than
individual scripts. Do you know roughly where is it? I think there
were some versions with this missing in the ini, which was later fixed.
I'm guessing that if ignore_user_abort is set to on, this could be
the culprit?
Would simply adding the following to the ini work?
Ignore user abort defaults to off, and doesn't necessarily help you if
the clients don't terminate their connections properly, or they're
actually trying to DoS you. I think your best bet is to either use
some lightweight detection in PHP (and maybe send an HTTP error header
if you're getting hit), or better yet, use a firewall if one is
available to prevent the connections from even getting to your
webserver and wasting its resources. (If your server is running on
Linux, iptables should be able to do what you need, and there are more
complicated solutions too.)
