Hello,

Since I have upgrade the apache 2.0. i can see that apache take all the time 50% off the processor.

24993 webuser   25   0 44636 1956 1932 R 76.8  0.4   7404:16 apache2                           
29805 webuser   25   0 35168 1204 1196 R 57.9  0.2  21718:59 apache2                           
24095 webuser   25   0 29452 1128 1104 R 52.4  0.2  23041:55 apache2

Some times 100% off the processor.

Here is the load average off my server : top - 19:41:02 up 30 days, 20 min,  3 users,  load average: 5.38, 5.41, 4.78

Is a P4 2.8 Ghz with HT, 512 RAM

[root@www phpsession]$netstat -tn | grep :80 | wc -l
12

12 people on my webserver and apache take this charge ???

[root@www phpsession]$emerge -pv apache

These are the packages that I would merge, in order:

Do you have any idea why apache take all the CPU ressources, with previous version and no modification on the php code that is present on the web server i never have this charge.

Emerge without threads.

The worker MPM is not supported for PHP.

USE"-threads" emerge -v apache
