Access to Webinterface blocked after a few minutes

[seyfeb]

Steps to reproduce

1. Download nextcloud zip
2. Extract into /var/www/nextcloud
3. chown -R apache:apache /var/www/nextcloud
4. Access Page via browser
5. Wait a few minutes
6. Access page again

Expected behaviour

The nextcloud setup page should be displayed again.

Actual behaviour

At step 4 I see the setup page, at step 6 I don’t see it anymore. When I systemctl reoad httpd, I can access the page again only to be at the same spot as before after waiting a short period.

I have no problems accessing other pages using PHP on the same server.

The issue seems to be resolved by not setting

EnableSendfile on

in Apaches httpd.conf.
