Thanks for the advice, cannot shut server down right now however. I 
changed statuscache.db from berkely-nosync to skiplist (to see if the 
error went away) but also deleted statuscache.db in between. All else 
has been skiplist or flat for a long long time.

The error in question started to appear after upgrade from 2.3.11 to 
2.3.12-p2 when I used berkely-nosync for the statuscache.

Would not the db.backup* files already be in the same stae, they are 
recreated every 30 minutes...?
