I had to look this post: https://forum.owncloud.org/viewtopic.php?f=17&t=32517

I just read it in detail and tested the following changes (without success):

1. A bug in Apache https://github.com/owncloud/core/issues ... -148380791
2. A too small "SSLRenegBufferSize" Apache setting https://github.com/owncloud/core/issues ... t-90508358
3. A too small "LimitRequestBody" Apache setting https://github.com/owncloud/core/issues ... t-68443113
4. Timeouts on server side https://github.com/owncloud/core/issues ... t-85709557
5. Just a temporary network issue https://github.com/owncloud/core/issues ... t-86418646

and:

1. owncloud server> as administrator> I have set all of the users to quota = UNLIMITED
2. The Following option added to my apache config: 10486000 SSLRenegBufferSize
   the apache config Was Located in /etc/apache2/conf.d/owncloud.conf, and is shown below:

---------------------------------- ------------- Conf.d ----------------------
Alias ​​/ owncloud "/var/www/owncloud/"

SSLRenegBufferSize 10486000
Options + FollowSymLinks
AllowOverride All

<IfModule mod_dav.c>
  Dav off
</ IfModule>

SetEnv HOME /var/www/owncloud
SetEnv HTTP_HOME /var/www/owncloud

# Just in case if .htaccess gets disabled
Require all denied
----------------------------- ----------------- End conf.d -----------------

3. etc / php5 / apache2 / php.ini has-been changed from 2M to 16G: upload_max_filesize = 16G

4. /etc/apache2/httpd.conf point to server-tuning.conf Where I ensured
   KeepAlive On
   MaxKeepAliveRequests 500
   KeepAliveTimeout 500

Restarted server: apache2 restart systemctl

/etc/apache2/conf-available/owncloud.conf:

Alias /owncloud "/var/www/owncloud/"
<Directory /var/www/owncloud/>
SSLRenegBufferSize 10486000

SetEnv MOD_X_SENDFILE_ENABLED 1
XSendFile On
XSendFilePath /tmp/
</Directory>

## impossible to synchronize new files. but if there are no new files, it works correctly ...

Very likely a duplicate of the still open issue here: #9832
