[Samba] Possible bug in nmbd.

[Pablo Marín Ramón]

Hi,

My nmbd daemon is dying with an internal error periodically. Samba
version is 2.2.7a (I think the latest stable) but I've tried with the
Samba package that came with my Linux distro (a Debian Woody) and it
failed with the same messages too.

Here goes the log.nmbd file:

As you can see, it works fine between 21:29:39 and 05:56:22. The server
has no load because it's from a university and on fridays nobody uses it.

My /usr/local/samba/lib/smb.conf file is this:

I've tested it with testparm and it says that it's correct.

smbd works without trouble.

BETELGEUSE (authentification server) works ok.

Before upgrading the system we had a Red Hat 6.2 with Samba 2.0.x and it
worked with exactlly the same configuration and without troubles.

If you need more details just say it.

Thanks for your efforts.

Best regards,
