Hi again ...
I need help, this morning I lost again the control of the server.
99% cpu and no answer from SSHD.
After webfarm will have manually rebooted the system, I need some help
from you to understand the problem.
It's happened 4 times already...

Hi ...
I use ubuntu-server jaunty with apache2 and php5.
I also use tomcat6 on the server but I still can't configure mod_jk to
use the jsp website on port 80.
I write you because every daemon's size of apache2 processes is big
from 35 to 55 megabytes.
So with a configuration like:
KeepAlive Off
<IfModule mpm_prefork_module>
StartServers 2
MinSpareServers 3
MaxSpareServers 15
MaxClients 100
MaxRequestsPerChild 5000
</IfModule>
I run out of memory in a 1Gb RAM server.
I also notice that in a 700 free Mb of RAM situation, after opening 10
websites toghether, the used memory never comes back to 700Mb.
It's like if apache creates those daemons that he puts on sleep
without freeing memory.
Can you help me to understand the problem?
