--- Comment #6 from Andrew N. <anot at onet.pl> ---
Looks like this issue was not fixed by now (Ubuntu bionic 18.04.3)

Same behavior as described with sqlite3 and strace:
...
fcntl(3, F_SETLK, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=1073741824,
l_len=1}) = 0
fcntl(3, F_SETLK, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=1073741826,
l_len=510}) = -1 EACCES (Permission denied) 

the second one fcntl works fine on local filesystem but not on cifs 2.10,
kernel 4.15.0-72

The workaround is to mount samba share with nobrl option 

Please adjust status of this issue, this should be CONFIRMED
