The issue

Short description of the problem:

working with ML 9.0-5 and Roxy 1.7.7 (dual upgrade for customer application).
I see the old issue from #850 is back again.

During bootstrap i see the following

ERROR: ADMIN-PATHNAMESPACEINUSE: (err:FOER0000) In-use database path namespaces cannot be deleted.: foo

from the error log

I see that the code from from my PR #852 was not accepted which might be the cause of this. I will have to check
