this same error comes after applying kb , stays same after applying manual steps described in kb article.

the wsusutil postinstall on , gives no errors:

2016-05-10 16:32:04  postinstall started
2016-05-10 16:32:04  detected role services: api, ui, services
2016-05-10 16:32:04  start: loadsettingsforservicing
2016-05-10 16:32:04  end: loadsettingsforservicing
2016-05-10 16:32:04  postinstall completed

wsus service starts stops intermittently.

as way of testing decided bring susdb wid external sql 2012. suspected update , postinstallation steps worked flawless. issue external databases if "index outside of bounds of array" thingy.

in case solution. me on our testenvironment play moving database.
