Здравствуйте уважаемые знатоки.
У меня раз в месяц стабильно падает VPS-ка и в логах показывается нехватка памяти которую вызывает python.
Где-то 3 месяца назад все это работало в дебаг режиме (manage.py runserver .......) а эти проблемы начались после того как я перенес все на uwsgi в emperor-mode,
Стабильная ошибка в логах следующая:

Запускаю вот такой строчкой:
/usr/local/bin/uwsgi --emperor /opt/config --emperor-nofollow --daemonize=/var/log/uwsgi.log
Конфиг вассала выглядит так:
[uwsgi]
uid = ................
gid = www
umask = 012
chdir = /opt/apps/%n/app
virtualenv = /opt/apps/%n/venv
master = true
threads = 2
socket = /var/run/uwsgi/%n.sock
logto = /opt/apps/%n/logs/uwsgi.log
processes = %k
harakiri = 120
max-requests = 200
env = DJANGO_SETTINGS_MODULE=app.settings
module = django.core.handlers.wsgi:WSGIHandler()
Подскажите пожалуйста в какую сторону делать дебаг чтоб найти ошибку. Спасибо
