Administration - Installation - Core: innodb_lock_wait_timeout and innodb_rollback_on_timeout and test with randomized questions

Hi, we recently had an issue where a test with randomized questions where ILIAS logged

HY000 SQLSTATE[HY000]: General error: 1205 Lock wait timeout exceeded; try restarting transaction in /var/www/ilias/Services/Database/classes/PDO/class.ilDBPdoMySQL.php:131

and the response times got very bad, while at the same time the system monitoring didn't show any notable load on the database or the ILIAS application.

Since nothing is rolled-back by default, should we set innodb_rollback_on_timeout?

Is this a know issue to ILIAS wtih tests with randomized questions?
