This bug was initially created as a copy of Bug #1928188

I am copying this bug because: 

It also affects DWH data collection and processing. Once the engine db is updated, we should also fix the dwh db and process.

Description of problem:
engine.log is flooded with messages of this kind. All values look greater than Integer.MAX_VALUE
