apache eat up too many ram per child
- by mrc4r7m4n
Hello to everyone.
I've got fallowing problem: Apache eat to many ram per child.
The fallowing comments shows:
cat /etc/redhat-release -- Fedora release 8 (Werewolf)

I know that you will say that there is nothing to worry about because swap is not use, but i think it's not use for now.

I guess thats all information needed to help me solve this problem.
I think the virt memory is to big, the same res. The consumption of ram is increasing all the time. Maybe it's memory leak because i see there is so many static modules compiled.
Could someone help me with this issue? Thank you in advance.
