Re: [cobalt-users] connections to HTTP port 80 are being rejected.

Hi Carrie, hi all,

thanks very much for the prompt reply.
It seems you hit perfectly the problem.

All the traffic is coming form a site (of mine) that is serving banner.
The hits are some 80.000 a day on 3-4 files.

Sincearly, I  think that the raq can handle those hits.
I agree with you when you say that there is some CGI program that track
hits, but looking to statistics
the client IP are wery dispersed, so that hits seems to be true or at list
not coming from the same IP.

I'm quite new to linux, so I have not perfectly understood what you mean
when you were speaking about wild child.
I had a look to pages that display banner. Those are no-content pages (just
few banner) and so, probably pop-up windows.
Is it possible that wild childs are origined when a user immidiatly close
that windows?
Do you think that lower KeepAliveTimeout can help(now it's 15)?
If not, what to do?

[Thu Nov 23 04:53:45 2000] [warn] child process 6080 still did not exit,
sending a SIGTERM
[Thu Nov 23 04:53:45 2000] [warn] child process 7933 still did not exit,
sending a SIGTERM
[Thu Nov 23 04:53:45 2000] [warn] child process 8711 still did not exit,
sending a SIGTERM
[Thu Nov 23 04:53:45 2000] [warn] child process 8714 still did not exit,
sending a SIGTERM

These [warn] messages seems to prof your thesis ( if I understood good about
wild child).
Thank  very much,


Filiberto


[OT] Until some days ago I had  20$ host account that was almost able to
serve the banners. Now I have a ded to improve performances....:-)
