I'm not sure about cause of the the problem, but I can write more.
When system (FreeBSD) is closed unexpectedly tdb files are corrupted.
After boot samba tries to start, but because of corrupted tdb files
it is impossible :(

Samba version 3.0.28a a tries to start, generates PANIC message, runs
a lot of smbd/nmbd processes and "eats" system resources. System is
not available from network, access to console is needed.

Older samba - I'm not sure, but I think prior to to 3.0.25a, for
example 3.0.24 - tries to start, generates panic message and doesn't
work, but system is stable.

Fast solution: kill all smbd and nmbd processes, delete all tdb files
from /var/db/samba/ directory, start samba ... should be ok. After
next unexpected system restart problem can back :( As I remember
older samba port (3.0.24) doesn't need manual remove of tdb files.
Command "/usr/local/etc/rc.d/samba restart" is enough.

Temporary solution: find old port, version 3.0.24 is OK, compile and
install. I found old ports in iso images of previous version of
FreeBSD.

Is it possible to check tdb files before samba start and make an
action (delete or repair the files) before start? How to do it?
