against Samba Version 4.4.16 synology)
2. Mount shared folder for 2 users eg.
sudo mount -t cifs -o
"vers=3.1.1,uid=1000,gid=1000,username=test,file_mode=0600,dir_mode=0700"
//NASIP/SHAREDFOLDER         /mnt

2. User1 starts to edit file on shared Folder 
3. at the same time User2 opens same file

User2 LO crashes, "loosing" all open documents.

server.
