Hi Alexey,
We need to see the status(''); output either for the v6 or v7 instance being
used.
Also, where did you see these "rollback" messages ?
Using the Bulk loader the load_list table shows the status of the load of
datasets and any errors reported loading them to you see any ?
The ld_meter function can also be used for monitoring the process of the bulk
loader operation including load rates as detailed at:
