Probably galera tested not so good

it worry me how much galera tested on the new buildbot, if you look here https://buildbot.mariadb.net/buildbot/grid?category=main&branch=10.5 you instantly see something happened with galera, on the new buildbot it also fails in 3 places 2 of which always fails)

It fails since e14d2b7974590bed801d1d1ba8191aa52a598961 and very massive on the old buildbot and almost invisible on the new one.
