Redmine

I am new to Redmine and Ruby, and also apologize in advance for my bad English.

After the transition from version redmine 3.2.0 to 4.1.0, problems are observed in work.

When you try to open a large project, one problematic above specified, problematic request comes to the database. This request destroys all free disk space (temporary mysql space) and the mysql base becomes unusable.

If you remove the extra "LEFT OUTER JOIN member_roles member_roles_members_join" then the request fulfills normally.
