Hello. After upgrading some DCs (in different domains) to 4.10, I'm trying to take backups with samba-tool. I'm not using "online" backups, as they require typing a password, so are not usable in a script. IIUIC, "offline" backups can be used even if Samba is running. However, they seem to get stuck: > root at dc1:~ # samba-tool domain backup offline --targetdir /var/tmp/DC1_Backup > Creating targetdir /var/tmp/DC1_Backup... > running backup on dirs: /var/db/samba4/private /var/db/samba...

.../private/secrets.tdb > samba 85298 root txt VREG 4,1302659313 430080 32007 /usr/jails/dc/var/db/samba4/private/secrets.tdb > samba 85298 root 35u VREG 4,1302659313 430080 32007 /usr/jails/dc/var/db/samba4/private/secrets.tdb IIUIC, it seems I have around 20 processes using secrets.tdb read/write, but no locks! So I tried stopping Samba completely: now no process has secrets.tdb open; still tdbbackup gets stuck in _fcntl!!! I'm open to suggestions... bye & Thanks av.

Please, find it below: (gdb) bt #0 0x0000000800fcdab8 in _fcntl () from /lib/libc.so.7 #1
