#29117 closed Bug (duplicate)

Excessive memory use when multiple objects retrieved using objects.get()

I recently discovered a bug in my application that is running on Django 1.8.18 with python 2.7.14. This code is used to retrieve names using a slug:

    record = record_class.objects.get(**filter_params)

except record_class.MultipleObjectsReturned:
    # deal with multiple records

Most names are single objects, but occasionally a name like 'not provided' will come through and return 1,000 results or more. In that instance, record_class.objects.get(filter_params) spikes in memory usage from 56mb to 344mb. On Heroku, running this query a few times quickly maxes out all available memory, and the app stays that way until the dynos are restarted.

I guess that could be solved by #6785. Do you have another proposal?
