XADM: Importing a Large CSV Hangs and Eventually Consumes All Memory

ID: Q222997

The information in this article applies to:

SYMPTOMS

DAPI batch import may stop responding (hang) or take a long time to complete and the computer may eventually run out of virtual memory space.


CAUSE

The import routines that check for modified values did not register the fact that previous values had already been checked. This caused an exponential growth in the number of passes (and memory allocation) made during the import.
