Hello,

Accidentally I have replacement MySQL server. We are using MySQL version 5.6.37 and Does not get any Server Error Log. Today I Do Upgrade to MariaDB 10.2.8 and Now lot of Server Error Log happened about Deadlock found when trying to get lock and Lock wait timeout exceeded. So this issue only happening with MariaDB.Everything was working fine prior to the change from MySQL to MariaDB, the issue would lie in the MariaDB configuration?I think we do mistake Upgrade to MariaDB. Now we are planning downgrade to the previous MySQL version but cPanel are not supported way to downgrade to the previous version After upgrade MySQL/MariaDB. So I think we need reinstall cpanel with Fresh-new Installation. Do we need reinstall cPanel/WHM with reinstall OS? I think we cant reinstall cPanel without a full O/S reload? Please let me know that How we can do this steps? I will do back up our sites data before reinstall process. Your continued support will be greatly appreciated.

Thanks

Hello,

Before reinstalling cPanel on a new server and migrating your accounts, you may want to troubleshoot the error messages you are receiving. I've sent a response to your other thread on this topic:

Deadlock found when trying to get lock

Thank you.
