Reproduce:
Remove a few thousand files from Nextcloud on your local machine (some GB of data), let client sync. After a minute or so nextcloud stops responding and the nginx log shows this a lot:
2016/11/09 00:22:47 [error] 2033#2033: *683 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: url.org, request: "GET /status.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.0-fpm.sock:", host: "url.org"
Restarting php7-fpm solves the problem until the client again attempts to sync.
I suspect that the reason is the new nginx version. But then I wouldn’t be sure how to fix this.
I have:
nginx 1.11.5
mysql 5.5.53
php 7.0.12
Windows 7x64
Nextcloud client
Linux mint 17.3 as the server OS
Nginx config:

Help would be appreciated.
I would open an issue but I am not sure if this is a client issue, a server issue or a documentation issue.
