The interval failures mean that after some failed access attempts (made periodically) engine locks the credentials with which the attempts were made.
From the your log it looks like recurring access attempts to the Gluster Volumes list have been made to host1.
It looks like at one point the admin profile became 'N/A' and then switched back to admin.
Did you do any changes to the admin user?
Can you unlock the admin user, reset it, restart engine and see if these problems recurr?

To unlock you can use (from a bash shell): "ovirt-aaa-jdbc-tool user unlock admin"

We didn't install OVN provider. What is the meaning of interval failures?

See this thread, as it seems you have installed latest 4.2.2.6
http://lists.ovirt.org/pipermail/users/2018-April/088314.html

Did you install/configure OVN provider too as described into the thread?

I see

and

Possibly you changed admin password and ovn was not synchronized...
