Hi Oalbps and Roi,
I have the very same issue. When I try to remove even 90 records the routine will leave about 5-10 records that should have been removed. I also used the function that Yisrael posted. I have tried running it in the backend as well as in page code and there is more consistency from the backend than from page code, but, still inconsistent for real world use.
This is a major issue!! The integrity of the data will be compromised greatly if these random results keep happening. have you guys had any luck understanding what’s going on here?
