python - How to run code that needs too much RAM on OpenShift? -

i have problem openshift. trying add django_geoip django app. however, when try initialize database, openshift kills it. think needing memory.
if run update code ./manage.py geoip_update(i tried running nohup), output:

downloading zipfile ipgeobase.ru... info:import:downloading zipfile ipgeobase.ru... extracting files... info:import:extracting files... updating locations... info:import:updating locations... updating cidr... info:import:updating cidr... 61% 

after 61% of cidr update crashes. if following log or logged in through ssh, disconects me:

i guess heavy memory usage. tried empty database , deleted log files sure not capacity problem(disk quota exceeded).
question is: how run command make work? may somehow limit needed resources?

well found out caused geoip creating django_geoip_iprange table, has around ~218 000 records. geoip loads these ips memory , stores them database. able import table django_geoip_iprange localhost, django_geoip should functional now.
additionally, should able use ulimit limit resources required. did not test yet.
