Server crashes - downloads php file

[Bogdan2288]

Hello,

I have a vps with 10 cpus and 60gb ram. From time to time something crashes and every site on the vps downloads a php file on refresh. It may happen one time after a few days or one time every day, it does not follow a pattern. If I restart the php-fpm service the issue goes away instantly. If I don't restart it takes a while to get back to normal. Does anyone know what may be the cause of the download? Or what logs to inspect? Thank you.

I would start with the apache error logs and the php-fpm logs. They can be found at:

/etc/apache2/logs/error_log

and

/opt/cpanel/ea-phpXX/root/var/log/php-fpm/error.log

Respectively

It only happens in PHP 7.3, in other versions it doesn't.

Based on that output your reaching the max children setting - this has nothing to do with the PHP version, its related to the domain itself. For the Process kill notifications - do you happen to be running opcache on php 7.3?
