Will try this when not that much users are working with the system, 
thanks.

As a workaround I switched to a ftp backend. That seems to work better, 
but I can see many lines like this in the horde log:

2017-06-22T07:44:56+00:00 WARN: HORDE [gollem] PHP ERROR: rewind(): 
stream does not support seeking [pid 30057 on line 1770 of 
"/usr/share/php/Horde/Mime/Part.php"]
2017-06-22T07:44:56+00:00 WARN: HORDE [gollem] PHP ERROR: fseek(): 
stream does not support seeking [pid 30057 on line 73 of 
"/var/www/horde/gollem/view.php"]

Is that something that can be ignored or what is causing this errors and 
what can / should I do to prevent them?

Ciao and thanks,

  Schoepp
