             Summary: mod_wsgi: Truncated or oversized response headers received from daemon process
                 Key: AIRAVATA-3363
                 URL: https://issues.apache.org/jira/browse/AIRAVATA-3363
             Project: Airavata
          Issue Type: Bug
          Components: Django Portal
            Reporter: Marcus Christie
            Assignee: Marcus Christie


mod_wsgi errors for the Django Portal when integrated with Custos:
```
[Tue Aug 11 18:59:24.552801 2020] [wsgi:error] [pid 8643] [client 68.51.122.242:51536] Timeout when reading response headers from daemon process 'aci.general.scigap.org': /var/www/portals/django-airavata-custos-integration/airavata-django-portal/django_airavata/wsgi.py, referer: https://aci.general.scigap.org/admin/users/

[Tue Aug 11 19:03:29.714533 2020] [wsgi:error] [pid 7967] [client 68.51.122.242:52587] Truncated or oversized response headers received from daemon process 'aci.general.scigap.org': /var/www/portals/django-airavata-custos-integration/airavata-django-portal/django_airavata/wsgi.py, referer: https://aci.general.scigap.org/
...
```

Turns out the problem is probably related to running C extensions in some Python modules. Just a guess but it might be the grpc libraries since those are new with the Custos integration. https://serverfault.com/questions/844761/wsgi-truncated-or-oversized-response-headers-received-from-daemon-process/844786#844786

The fix was to add 
```
WSGIApplicationGroup %{GLOBAL}
```
to the virtual conf file.
