At first: I get this error message only about twice a day (smbstatus is
executed every 10 seconds) and the "offset" number every time changes.
But the issue with a "ghost" user is more frequent.
I read the source of smbstatus and I think that delete
/var/run/samba/sessionid.tdb will be enough. In my tool I use "smbstatus
-p" and in this case any other file is not used.
I already tried to stop samba, delete this file and then start samba.
New empty sessionid.tdb was created but nothing changes.
Maybe I will try your advice about delete and backup all tdb files but I
have to wait for some time for testing when the system is not in use.
