Please help us by providing the following info. Before posting please also check the pinned "Known issues" threads and make sure that you're running the latest available version for your oC release: https://owncloud.org/changelog/
Steps to reproduce
ownCloud should work, or at least complain about what doesn't work
It locks up, uses 100% of one CPU, and then eventually I get a
504 Gateway Time-out from NginX
Operating system: Ubuntu Server 16.04 (was Ubuntu Server 15.10)
Web server: NginX + PHP7.1-FPM (was NginX + PHP7.0-FPM)
PHP version: 7.1.0beta2
ownCloud version (see ownCloud admin page): One patch from the latest version I think (can't check obviously)
Updated from an older ownCloud or fresh install: not during this migration process
ownCloud log (data/owncloud.log, see https://central.owncloud.org/t/how-to-find-webserver-or-oc-logfile-enable-php-logfile/808):
Special configuration (external storage, external authentication, reverse proxy, server-side-encryption): Reverse proxy: Nginx sits in front of PHP7.1-FPM.
Integrity status for oC9+
Sorry, can't check this.
Login as admin user into your ownCloud and access http://example.com/index.php/settings/integrity/failed paste the results here.
I'm performing a server migration, and while I've been moving ownCloud I've hit upon a snag. After setting up NginX and PHP7.1-FPM and moving across the NginX and PHP FPM config files, ownCloud now locks up, uses 100% of one of my CPUs, and times out eventually.
Can anyone help me please?
