FreeBSD-12.1p7 jail running Samba-4.10.15 on ZFS.
When I run 'samba-tool domain backup offline targetdir=/tmp' I see this:
running backup on dirs: /var/db/samba4/private /var/db/samba4 /usr/local/etc
Starting transaction on /var/db/samba4/private/secrets
At which point samba-tool enters a permanent wait state.
86064 root 1 52 0 131M 78M wait 3 0:01 0.00% python3.7
Trace shows this:
. . .
--- modulename: subprocess, funcname: __enter__
subprocess.py(845): return self
subprocess.py(340): try:
subprocess.py(341): return p.wait(timeout=timeout)
--- modulename: subprocess, funcname: wait
subprocess.py(1016): if timeout is not None:
subprocess.py(1018): try:
subprocess.py(1019): return self._wait(timeout=timeout)
--- modulename: subprocess, funcname: _wait
subprocess.py(1623): if self.returncode is not None:
subprocess.py(1626): if timeout is not None:
subprocess.py(1649): while self.returncode is None:
subprocess.py(1650): with self._waitpid_lock:
subprocess.py(1651): if self.returncode is not None:
subprocess.py(1653): (pid, sts) = self._try_wait(0)
--- modulename: subprocess, funcname: _try_wait
subprocess.py(1610): try:
subprocess.py(1611): (pid, sts) = os.waitpid(self.pid,
wait_flags)
And that is where it stops. Is this caused by a configuration issue? Is so
then what?

Otherwise, work out which commend it is waiting on (the child) and what lock that is waiting on (lslocks on linux is what I used to debug this stuff).
