python 2.7 - intermittent but frequent NoReverseMatch error from deployed django application -


i have application deployed @ http://opencalaccess.org/ccdc/latest/

this colo running ubuntu 14.04 lts.

if hit this, may blank page says "server error (500)" , nothing else. may noreversematch exception. if continue fetch on url, work. may take 3 times, seems take no more 5 attempts. , works, eventually.

weird.

i depend on 2 packages building. moved them around several times , at:

/usr/local/lib/python2.7/dist-packages

and

$ cat wsgi.py  import os import sys  os.environ.setdefault("django_settings_module", "ccdc.settings")  sys.path.append('/var/www/opencalaccess_org/ccdc') sys.path.append('/var/www/opencalaccess_org')  django.core.wsgi import get_wsgi_application application = get_wsgi_application()

i did not have change settings.py file.

$ cat urls.py django.conf.urls import patterns, include, url django.conf import settings django.contrib import admin admin.autodiscover()  urlpatterns = patterns('',     url(r'^', include('calaccess_campaign_browser.urls')),     url(r'^admin/', include(admin.site.urls)),     url(r'^static/(?p<path>.*)$', 'django.views.static.serve', {         'document_root': settings.static_root,         'show_indexes': true,     }), )

what should @ here? suggestions? other entry points have same problem. , work also.

from /var/www/opencalaccess_org/ccdc/settings.py file:

installed_apps = (     'django.contrib.admin',     'django.contrib.auth',     'django.contrib.contenttypes',     'django.contrib.sessions',     'django.contrib.messages',     'django.contrib.staticfiles',     'django.contrib.humanize',     'calaccess_raw',     'calaccess_campaign_browser',     'tastypie', )

and
