Hello, I installed a Mariadb environment version 10.11.11 with Galera Cluster on three VMs. For a few months I have randomly and intermittently errors of the type shown below or reports of corrupt indexes:

Recreating the index with the optimize table command "table_name"; I can restore operation.
Do you have any suggestions for me?
