You need a system administrator to solve a bug

Hello! You need a system administrator to identify why sometimes 502 bugs pop up and fix the problem:

/var/log/atop/ - logs on server errors for every number here. We need for the 7th number from 19.45 to 19.53 (at that time there were lags that appeared due to the fault of the server).

And also to do it:
php.ini find the error_reporting and set it in E_ALL. error_reporting = E_ALL
