Is this normal ( from memory consumption point of view)
root 28204 5.5 2.5 51816 26604 ? Ss 03:00 0:00 /usr/sbin/httpd
apache 21245 0.0 2.5 51816 26628 ? S 03:00 0:00 \_ /usr/sbin/httpd
apache 14177 0.0 2.5 51816 26628 ? S 03:00 0:00 \_ /usr/sbin/httpd
apache 27735 0.0 2.5 51816 26628 ? S 03:00 0:00 \_ /usr/sbin/httpd
apache 2257 0.0 2.5 51816 26628 ? S 03:00 0:00 \_ /usr/sbin/httpd
apache 24352 0.0 2.5 51816 26628 ? S 03:00 0:00 \_ /usr/sbin/httpd
apache 11583 0.0 2.5 51816 26628 ? S 03:00 0:00 \_ /usr/sbin/httpd
apache 3574 0.0 2.5 51816 26628 ? S 03:00 0:00 \_ /usr/sbin/httpd
apache 9181 0.0 2.5 51816 26628 ? S 03:00 0:00 \_ /usr/sbin/httpd

22.5% of my memory goes to apache? is that normal?(and just restared the thing.... it can go up to 12-14% a child)

Using:
Plesk 8.01
ASL
Centos 4.x current

Thanks

How much ram do you have on the box? We've run into a really weird bug with apache that can cause it to not free up memory on the newer versions. It doesn't happen on RH9, which is our primary development environment for mod_security.

1GB and yes this must be it.... it eats up all my ram and keeps it... sometimes crashing... my version is:

Installed Packages
Name : httpd
Arch : i386
Version: 2.0.52

Yep, shoot this to the ASL support list (support@atomicorp.com), I dont maintain the mod_security piece, and the folks that do don't read these forums. So definitely email support whenever you run across problems like this in the future.
