I be one of them. ctx-16-1 so far been good but only been running for
about 24 hours. I ran that script without problems with ctx16-1
however I never tried it on ctx16 so can't 100% verify that it is
infact fixed based on running this script. But Jonathan said this
script would crash.

I been running 1 copy of the script inside a virtual server, one
script is running on the virtual master and have a third script
running on a different system pulling a complete webpage from one of
my domains on a virtual server.

Actually I'm currently still running it but I pulled up the page more
then 15k, 5k, 3k on the different machines without any hickups as of

Ahh can't wait for that especially the vserver memory limitation file
handle limitation is also nice but right now it seems memory
limitation is what I'm missing the most (besides a context based
quota which I not yet tested out the one that is available out there
the warnings almost scares me -lol-)
