Google Chrome console show http 500 error after saving a schedule and modal form won’t close automatically, but after closing it manually the schedule has been saved.
I can’t figure out where to look for, apache2 log show nothing.

What it is your php.ini config?
More specifically, these parameters:
max_execution_time
max_input_time

3 
PHP 7.2.17-1+ubuntu14.04.1+deb.sury.org+3
max_execution_time = 600
max_input_time = 600

You need to check VirtualHost error log, not apache log.

<VirtualHost *:Port>
ServerName www.domain.com
ServerAlias domain.com *domain.com
DocumentRoot /var/www/html/domain.com

ErrorLog /var/www/html/domain.com/log/error_log
CustomLog /var/www/html/domain.com/log/access_log common

Thats what I did.

This is Vhost file:

<VirtualHost *:80>
        ServerName xibo.dipaula.com.br
        ServerAdmin ti@dipaula.com.br
        DocumentRoot /var/www/xibo/web
        KeepAlive Off
        XSendFile on
        XSendFilePath /var/www/xibo/uploads
        <Directory /var/www/xibo/web>
        # Other directives here
            AllowOverride All
            Options Indexes FollowSymLinks MultiViews
            Order allow,deny
            Allow from all
            Require all granted
        </Directory>
        ErrorLog ${APACHE_LOG_DIR}/xibo_error.log
        CustomLog ${APACHE_LOG_DIR}/xibo_access.log combined
</VirtualHost>

I’ve enabled PHP error log and xibo_error.log show nothing.
xibo_access.log show this line:
192.168.2.5 - - [06/Nov/2019:15:46:03 -0300] "PUT /schedule/18 HTTP/1.1" 500 184 "http://xibo.dipaula.com.br/schedule/view" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.87 Safari/537.36"

I wonder if isn’t this “PUT” method the culprit.

Are you schedule a repeated event?
I did some tests. If I schedule a repeated event every 20 min without end time(forever), the CPU usage goes up to 90% (only a few seconds).
See the pictures

Normal usage.

Just after I pressed save button

Could you check CPU usage while you press save button?

I’m not scheduling a repeated event, there is no CPU spike, I don’t think it’s related.

Chrome console point to this jquery.js block line 9837:

try {

					// Do send the request (this may raise an exception)
					xhr.send( options.hasContent && options.data || null );
				} catch ( e ) {

					// #14683: Only rethrow if this hasn't been notified as an error yet
					if ( callback ) {
						throw e;
					}
				}

I really have no idea, I’m sorry.
