archive.php cannot finished
every time after 25min I get "General error: 2006 MySQL server has gone away"
I suspect sql command timeout
Any ideas?

here is the console output

[root@zeus ~]# php /var/www/vhosts/sexblue-box.gr/httpdocs/piwik/misc/cron/archive.php --url=http://www.sexblue-box.gr/

Using this 'archive.php' script is no longer recommended.
Please use '/path/to/php /var/www/vhosts/sexblue-box.gr/httpdocs/piwik/console core:archive --url=http://www.sexblue-box.gr/' instead.
To get help use '/path/to/php /var/www/vhosts/sexblue-box.gr/httpdocs/piwik/console core:archive --help'

If you cannot use the console because it requires CLI

try 'php archive.php --url=http://your.piwik/path'
