Hallo NG,

I'm running an Apache 1.3.20 on a Slackware Linux 2.2.19. I have varios
virtual hosts in my httpd.conf and everything is going quit well.

But:

If i run "lsof -c httpd" i have over 13.000 open files on 22 Child-Processes
of the httpd Server. Every Child Process opens more then 600 Files, most of
it are Log-files where someone is opend 2 or 3 times.

Does anybody have an idear of what is going on?

To see the real number of open files (not memory maps and dlopen'ed modules) look for each pid in /proc/pidnumber/fd. There you only have symlinks to open files and sockets.

And error-log is generaly open as stderr (fd 2) and another file descriptor.

Anyway, at 600 open files per child reported by lsof, it looks like your server is really visited (lots of active connections at any moment) and that should be good (unless this consumes much bandwidth than you can afford).
