Well that could be the problem - I'm 99.99% positive we do not execute
so many transactions - may be 30-40 thousand per day and that's only for
one relatively busy DB. The example database ("xxx1") you've chosen is
not used at all. As most of the other databases in that cluster.

And another observation (closely related IMO): when I login on another
development server/cluster and execute the same query I get an increment
 for every database for every query execution. But there the version is
8.0.1.
