[Samba] TDB Corruption.

[Linux Addict]

Hello, I have relatively a large setup where RHEL 4 authenticating MS 
W2K3 R2. Every often a host may not be able to authenticate due tdb 
corruption and we had to rm the *.tdb and files and restart the winbind 
which would  create fresh tdb files.  I guess Redhat acknowledged  the  
issue here. http://kbase.redhat.com/faq/docs/DOC-4842    My question is, 
is this something caused by samba itself or the underlying OS. If samba, 
are we tracking this?  I know I can use LDAP backend, but I am using RID 
to eliminate layer of admin work by not entering UIDs for each user.
Any hint is appreciated.

Thanks.
