I use i-MSCP 1.2.2 (Build: 20150212 Codename: Andromeda).

The global apache conf is in /etc/apache2/apache2.conf ?

I have exactly 70 domains with "average" small traffic (cca. 100 visitor/day/domain).

Here are the main settings:

Code

MaxKeepAliveRequests 100
KeepAliveTimeout 5
<IfModule mpm_worker_module>
StartServers 2
MinSpareThreads 25
MaxSpareThreads 75
ThreadLimit 64
ThreadsPerChild 25
MaxClients 150
MaxRequestsPerChild 0
</IfModule>
<IfModule mpm_prefork_module>
StartServers 5
MinSpareServers 5
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 0
</IfModule>
<IfModule mpm_event_module>
StartServers 2
MinSpareThreads 25
MaxSpareThreads 75
ThreadLimit 64
ThreadsPerChild 25
MaxClients 150
MaxRequestsPerChild 0
</IfModule>

Hi,

that are the standard settings. Check with

Code

apache2 -V

which Server MPM is used. I think it is "Worker". So you have only edit the settings in <IfModule mpm_worker_module>. Raise MaxClients to 250 and have a look to your server.

You have right!

I'd suggest you:

<IfModule mpm_worker_module>
ServerLimit 40
StartServers 8
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxClients 1000
MaxRequestsPerChild 4000
</IfModule>

Maybe, enought

Bad idea.

Hello

I am having a similar problem.

I have:
# Ubuntu 14.04 (Upgraded from Ubuntu 12.04)
# i-mscp 1.2.9
# php5-fpm selected

Suddenly my website "domainA.de" is not reachable anymore. The Server ist up and running so i can log in via SSH.
Another Domain "domainB.de" which is on the same Server is running correctly.

I dont know which log files can i check.

I have check file: /var/log/apache2/domainA.de/error.log

Which has a lot of entries:
Other Websites dont have those entries...!
