Hello,
I have Ubuntu Server 12.04.3 LTS and Plesk 11.5.30 Update #18.
This is a Virtual Server with 2 vCPU (4,80 Ghz total), ram 4 Gb.
The server has 13 domains.
Average server utilization is this: CPU 10%, RAM 50%, active processes 110-115
Occasionally the sites are inaccessible and you can not connect to the server console.
At that moment, the active processes are 250, the CPU is at 100%.
I'm trying to understand the cause.
On /var/log/apache2/error.log I find this line (when the server is overloaded):
[Tue Oct 15 12:42:20 2013] [error] server reached MaxClients setting, consider raising the MaxClients setting
This could be the cause?
Can you help me ?
Tnx in advance
Manuel
