samba - Oct 2007 - Empty secrets.tdb.

Hi all:

I have a FTP server combined with samba server. Pam_smbpass.so is used to
provide authentication. Everything works fine in the beginning. But after a
period of heavy access from FTP, the login will fail. I found the problem is
resulted from secrets.tdb. It became an empty file (I use tdbdump to check the
content). Pam_smbpass.so rejected the authentication when it can=A1=A6t check
the SID in the secrets.tdb. My samba version is 3.0.25c. Previous version is
3.0.21c, and it did not have the problem.

Thanks for all advice,
