Hi everyone,

In my environment I have a total of 4 directory servers, 2 multi-masters in production (ServerA, ServerB) and 2 multi-masters to test with (ServerC, ServerD).  Basically here's what I did:

Took a backup of one of the production directory servers, ServerA

Copied ServerA's backup to ServerC (test).

Deleted the replication agreement on ServerC to ServerD (but not the agreement from ServerD to ServerC)

Ran /usr/lib64/dirsrv/slapd-ServerC/bak2db 2011_12_29_15_27_35

The restore started, and never stopped running.  I eventually killed it and tried again, this time capturing the output:

...

The output just continues to display those same "Del Index Config Entry" lines until I stop it.
Which same lines?  You mean after parentid, it starts over again with cn=aci?  And it just keeps on doing that over and over until you abort it?  That's very strange that it is omitting cn=seealso and cn=sn and cn=telephoneNumber and cn=uid and cn=uniquemember which are the other standard default indexes.

Yes after parentid it starts again at aci and just keeps displaying those same 18 lines.  The indexes above show up as "system indexes" while the ones you listed are additional indexes if that means anything.

What version of 389-ds-base?  What platform?

389-ds-base-1.2.9.9-1.el5
RedHat EL 5.5

After that I tried deleting the replication agreement on ServerD to ServerC, then tried restoring one of my original ServerC backups but it did the same thing.
I have had this problem before trying to do restores of backups from the same server and I thought it had something to do with having replication enabled so I would disable it before doing restores (like above)...thought that fixed it but seems like it hasn't.  Does anyone know what I'm doing wrong?

Thanks for the help
I've filed https://fedorahosted.org/389/ticket/4 to track this issue.  Please feel free to add yourself to the CC list (you'll need a Fedora account to do so - see https://fedorahosted.org/389/wiki) and add any comments

 Thanks, I made an account but not sure how to get on the list so I'll just bookmark and follow.  Thanks again.
