Ok, I see.  I'm not sure if directory server auto-recovery is possible 
with this sort of failure.  You might be able to use the berkeley db 
command line utilities to upgrade and/or recover your database files.  
http://www.oracle.com/technology/documentation/berkeley-db/db/utility/index.html 
- you may have to figure out which version of bdb you are using, then 
find the appropriate documentation - rpm -qi db4 or rpm -qi db4-utils.
You might try db2ldif to export your data, then re-import using ldif2db, 
but that would force a replication re-init anyway.
