I check with VPS provider - no problem from them.

What should I do now?

Is it possible that my site received too much traffic?

[MRatWork]

Nothing with web server and php setting because your cp.yourdomain.com appear perfectly.

It's possible problem with high-traffic website, especially limiting value for webserver (apache). Try select 'optimize' for 'apache optimize' in 'webserver config'.

[henry]

Done!

Problem remains.

[MRatWork]

Try change 'mod_php_ruid2' to 'php-fpm_event'.

[henry]

Try change 'mod_php_ruid2' to 'php-fpm_event'.

Set this and after few minutes, web page loading back to normal.
Thank you very much
