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)
free -m:
total used free shared buffers cached Mem: 3566 3136 429 0 339 1907 -/+ buffers/cache: 889 2676 Swap: 4322 0 4322
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.
