Fails to schedule jobs for snapshot harvest even though message has been received that index is ready.

Got this log-entry in the harvestjobManager:

INFO: Got message from the IndexServer, that the index is ready for harvest # 2

However the isindexready field is false

select * from fullharvests;
harvest_id | maxobjects | previoushd | maxbytes | maxjobrunningtime | isindexready
