Memory continues to increase

Hello, I have continuous crash problems due to a disproportionate use of RAM. I have now reinstalled the OS CentOS 6 - installed VestaCP with this config:
bash vst-install.sh --nginx yes --apache yes --phpfpm no --named no --remi yes --vsftpd yes --proftpd no --iptables yes --fail2ban no --quota no --exim yes --dovecot no --spamassassin no --clamav no --softaculous no --mysql yes --postgresql no --hostname xxxxxx --email xxxxxx --password xxxxxxx

Now, with nothing installed, only VestaCP since I still have to restore the backup I see the same problem, memory keep increasing, it started from 750 MB and now in 30 mins is at 5 GB .... It has no sense i'm stuck.

My VPS is 2 cores up to 2GHz each with 8 GB RAM

this is my.conf:

Just wondering,
You have 8 start servers on prefork....but on a 2 core system . Should this be same as number of cpu/cores like you have with mpm worker?

Perhaps you could drop max requests per child (currently 4000 in mpm worker) back to half that amount. I thought 2000-2500 was enough. I have one of my virtualmin systems running mpm event with this value at 1000 (it's only a small vps though)

Are you running prefork or worker btw?

Do you have a swap file enabled?
