Issue Many cronjob hourly problems after upgrade to obsidian

Hi friends

I'm worried about this issue after upgrading a productive server from Onyx to Obsidian in Centos 7 Linux. The process was fine (doing some adjustements after upgrade) but every hour I get this email from cronjob that worries me:
/etc/cron.hourly/plesk-php-cleanuper:


Failed loading /usr/lib64/php/modules/ioncube_loader_lin_5.4.so: /usr/lib64/php/modules/ioncube_loader_lin_5.4.so: undefined symbol: zend_block_interruptions PHP Warning: PHP Startup: Unable to load dynamic library 'mysql.so' (tried: /opt/plesk/php/7.2/lib64/php/modules/mysql.so (/opt/plesk/php/7.2/lib64/php/modules/mysql.so: cannot open shared object file: No such file or directory), /opt/plesk/php/7.2/lib64/php/modules/mysql.so.so (/opt/plesk/php/7.2/lib64/php/modules/mysql.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library 'mysqli.so' (tried: /opt/plesk/php/7.2/lib64/php/modules/mysqli.so (/opt/plesk/php/7.2/lib64/php/modules/mysqli.so: undefined symbol: mysqlnd_global_stats), /opt/plesk/php/7.2/lib64/php/modules/mysqli.so.so (/opt/plesk/php/7.2/lib64/php/modules/mysqli.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_mysql.so' (tried: /opt/plesk/php/7.2/lib64/php/modules/pdo_mysql.so (/opt/plesk/php/7.2/lib64/php/modules/pdo_mysql.so: undefined symbol: mysqlnd_allocator), /opt/plesk/php/7.2/lib64/php/modules/pdo_mysql.so.so (/opt/plesk/php/7.2/lib64/php/modules/pdo_mysql.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library 'wddx.so' (tried: /opt/plesk/php/7.2/lib64/php/modules/wddx.so (/opt/plesk/php/7.2/lib64/php/modules/wddx.so: cannot open shared object file: No such file or directory), /opt/plesk/php/7.2/lib64/php/modules/wddx.so.so (/opt/plesk/php/7.2/lib64/php/modules/wddx.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

Is this a bug? or do I have to do any workaround?

Any help is so appreciated!!! Thanks so much
