Hello, I'm running Samba 3.2.5 on Debian, with tdbsam backend. For the past few days, I've had trouble with starting Samba (which I do routinely once a day) but with users unable to login on Windows workstations. When this happens, the current smbd.log shows no activity (not even the "starting samba" event) and the previous day's smbd.log shows entries like these: [2009/10/24 19:41:38, 2]
