We have a dedicated server running Postgres 12 database with this configuration:

Model: HPE ProLiant DL580 Gen9
CPUs: 4*Intel(R) Xeon(R) CPU E7-4850 v3 @ 2.20GHz
Ram: 128 GB
Ubuntu 18.04.4 LTS
Postgre SQL 12

The problem is that the CPU usage never reach 50%. When I checked ZABBIX logs found out when CPU usage becomes more than 40% COU Softirq time increases as you see:

When I checked PRTG Logs, saw something weird; The utilization of some CPUs are up to 80% but most of them are less than 20.

What's happenning here? How can I use all of my CPUs?

I installed Kamailio 4.0 on a Ubuntu-Server 14.4 and a MySQL Server on another Ubuntu-server using Virtualbox.

192.168.0.131: MySQL Server

192.168.0.141:Kamailio 4.0

I changed the address of database from localhost to 192.168.0.131. But it does not connect. I googled a lot but could not find the solution. What information do you need to help me?

I have access to server with this command:

mysql -h 192.168.0.131 -u kamailio -p

Some Outputs:

ahmad@ubuntu2:/$ kamctl start

INFO: Starting Kamailio :

ERROR: PID file /var/run/kamailio.pid does not exist -- Kamailio start failed
