The first time you run Task History Cleanup, it may fail with these error messages:

{code}Could not remove TaskSchedule object for task{code}
and
{code}violation of foreign key constraint{code}


{kb-resolution}

Workaround:
Re-run Task History Cleanup after the first failed attempt in order to remove the remaining tasks that were not deleted on the first attempt.
