Subject Re: [users@httpd] Too Many Open Files

It was thus said that the Great Kerry Wilson once stated:

  Yes.  You'll want to run "ulimit -a" and check the value for open
files---you'll see this is less than the file-max value.  What I've done is
modify the startup script for apache (on my system, it's /etc/init.d/httpd)
to add:

	ulimit -n 8192

just before starting the web server.  This increases the allowed open files
for the webserver from the default (1024)---and this will *only* apply to
the webserver.

  -spc (Which solved the problem for me)
