Hi - just downloaded Apache 2.2 from ApacheLounge and installed on my Window XP Pro box. I changed conf so I could read the manual and then fired-up "httpd" process. Even though I could read the manual with http://localhost/manual I noticed that CPU was ramped pretty high (I'm running a 3.2Ghz Pentium 4 HT with 2GB RAM so it should be plenty.

What does this mean from error.log file?

...


So I killed it and then heavy CPU load went away.

Any ideas?

Thanks!

The messages are quite clear.

Did you tried the Win32DisableAcceptEx directive ?

I had the same problem. After I uninstalled the app "Steganos Internet Anonym ..." the problem has gone. Without to include the Win32DisableAcceptEx directive to httpd.conf!
