Hm, I looks as if I was a bit to quick here, it just hung got again :-(. 
And this time without anyone competing for this lock, only the lock on 
the glue suffix entry.  I wonder if it can be the upgrade from db 4.6.18 
to 4.6.21.1 I dit yesterday that is the real problem.  I'll try to 
downgrade and see if that helps.

Please put this case on hold.  Sorry!
