----------------------+-------------------
 finally running a current master with out-of-the-box config again on a
 prod system, seems like our default workspace_backend is too tight.
 And something is wrong with uppercasing the ws ID on overflow.

 will bump workspace_backend to 32k and report back if it helps.
