Hi,
I'm used to the "transaction collision" warnings, but it seems we're
getting more and "Exception sending Rollback" exception reports in the
log. What triggers these exceptions and what is the consequence if any
regarding the data consistency in the HRD?
Exception sending Rollback:
Traceback (most recent call last):

api/datastore.py", line 2505, in _DoOneTry
