I get an intermittent warning stating 'Background thread resigning due to memory pressure' when processing less than 1000 items.  If I receive this warning, the tool will freeze when it is closing the remaining threads (it often displays a negative number in the output).

Why do I receive this warning and how can I prevent the tool from freezing?
