Memory continues to increase

Posted: Thu Jun 06, 2019 9:32 am

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?

Maybe all is cache ? so if is that not is bad

But you need see your mysql is configured to use 2GB of RAM + PHP memory, if you use fastcgi you will use much memory in vestacp if you not configure it well

I not see that bad, not know if you use all it in cache, and we not know what page sites you host and what traffic and resource usa they have.

Irecomend you review all it per ssh,free -m / top and orther tools and see real memory usage + cache usage
