I used owncloud up to 9 on debian 8 from years with no problem. To upgrade I made a fresh installation of debian 9 initially with owncloud X and finally with nextcloud. All works but I have the same occasional problem on both software when I upload files from the client application. Sometimes the system works for hours, other times the system works for seconds before to crash. Attention: I use a local host storage to write the users data (shared by the virtualbox host with nexcloud machine- solution used successfully for years in owncloud9).
Nextcloud version _12.0.5:
Debian 9.3 on virtualbox 5.2.6 r120293 (Qt5.7.1)
Apache/2.4.25 (Debian)
PHP 7.0.27-0+deb9u1 (cli) (built: Jan 5 2018 13:51:52) ( NTS )
mysql Ver 15.1 Distrib 10.1.26-MariaDB, for debian-linux-gnu (x86_64) using readline 5.2

I have also the problem 2:

As workload I will have 4 users that sync with the client application about 70GB each with thousands of little files… actually I’m testing with one.
Thank you so much who will help
