            Bug ID: 296231
           Summary: databases/mariadb114-server-11.4.12 sets
                    innodb_buffer_pool_size_max to 8 TB by default
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: Individual Port(s)

If you use the InnoDB Storage Engine on MariaDB, it tries to reserve
innodb_buffer_pool_size_max amount of virtual memory on startup. According to
MariaDB decumentation, if no value for innodb_buffer_pool_size_max is defined
in the configuration, it defaults to the same value as innodb_buffer_pool_size
or to 0 if no innodb_buffer_pool_size is configured either. I can confirm this
behaviour with mariadb114-server-11.4.10. However on mariadb114-server-11.4.12
innodb_buffer_pool_size_max defaults to 8 TB if not explicitely set. In
resource-limited environments this leads to all sorts of interesting
consequences, rendering the system completely unusable in at least one case.
