CIFS problem in sid

Hi all,
I'm having an intermittent problem with samba mounts from sid on one
server. Once a week or so, a connection to one of the shares hangs.
Shares on other servers are fine, shares on the problem server are fine
from another client, it's just connections from this particular
workstation to that particular server which die. It is possible, of
course, that if I was accessing one of the other servers at the time
the fault occurs, it might kill those shares.
In the fault state, which I have only been able to fix by rebooting the workstation, Thunar does not open at all, presumably as it has shortcuts
to the offending shares, mc runs but hangs if I try to open the
directory containing the offending mount points, apparently
indefinitely. I can't close mc to see if the terminal shows an error, I
must close the terminal.
The mounts are still shown by the mount command, any attempt to umount
or remount one of the shares hangs, again apparently indefinitely, so I
get no error message.
Mounting is handled by systemd, as far as I know, but I can find no
systemd unit which refers to cifs. ps aux returns a cifsd entry, but
shows the status as 'D', and shows no parent. It also shows four
kworkers which refer to cifs. None of these processes can be killed, so presumably they are zombies.
I assume this is a temporary bug, which will eventually be fixed, but I
can find no information at all to send in a bug report, other than 'it
doesn't work'. What I'm looking for here is suggestions about what to
look for to provide some useful bug information. There's nothing in any
log, of course, either on client or server.
Is there anything I can restart which is likely to wake things up?
Rebooting isn't a great problem, but it just seems like a Windows way
of fixing things.
