Ignore_user_abort error

Hi!

I just install nextcloud and found this error in the log.

Nextcloud version (eg, 12.0.2): 14.04
Operating system and version (eg, Ubuntu 17.04): Ubuntu 18.04
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.34 and Nginx 1.15.3
PHP version (eg, 7.1): 7.2

The issue you are facing:

ignore_user_abort() has been disabled for security reasons at .../nextcloud/apps/dav/appinfo/v2/remote.php#28

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Login as admin
  2. Open log page

The output of your Nextcloud log in Admin > Logging:

ignore_user_abort() has been disabled for security reasons at .../nextcloud/apps/dav/appinfo/v2/remote.php#28

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

<?php
$CONFIG = array (
  'instanceid' => 'xxx',
  'passwordsalt' => 'xxx',
  'secret' => 'xxx',
  'trusted_domains' => 
  array (
    0 => 'xxx',
  ),
  'datadirectory' => 'xxx',
  'dbtype' => 'mysql',
  'version' => '14.0.4.2',
  'overwrite.cli.url' => 'xxx',
  'dbname' => 'xxx',
  'dbhost' => 'localhost',
  'dbport' => '',
  'dbtableprefix' => 'xxx',
  'mysql.utf8mb4' => true,
  'dbuser' => 'xxx',
  'dbpassword' => 'xxx',
  'installed' => true,
);

Please advice.
Thank you!
