In my production envrionment, a secondary stay STARTUP2 state all the time because of dead lock.
Thread1
after sync from primary, seconday call AuthzManagerExternalStateLocal::initialize to reload auth, it hold AuthzManagerExternalStateLocal::_roleGraphMutex lock, and then try to acquire read lock of admin database
Thread2
a request lead to creation of admin.system.profile, which will hold write lock of admin databaseļ¼and then try to acquire AuthzManagerExternalStateLocal::_roleGraphMutex lock.
