I'm going to attempt this upgrade again tomorrow morning.  As I look 
closer at the contents of the existing var/locks directory, I wonder if 
some of the files are no longer in use:

Same thing for the private directory:

[root at chernobyl private]# dir
-rw-------   1 root     root       24576 Jun 26  2010 passdb.tdb
-rw-------   1 root     root        8192 Apr 15  2006 secrets.tdb
-rw-------   1 root     root           0 Aug 31  2005 smbpasswd

Can some of these files be removed when I upgrade to 4.3.3?  Samba was 
restarted on Jan 1 at 10:27am.

Thanks,
