corrupt id2entry.dbb

[mark@smartmonsters.com]

Folks:

I have what appears to be a corrupt id2entry.dbb file.  Symptoms:

--> "ldbmcat id2entry.dbb > ldif" dies with a segmentation fault.  The 
resulting ldif file ends with a couple of screens of these garbage 
characters: "Û¶mÛ¶mÛm".

--> ldapsearch returns incomplete results.

--> the id2entry.dbb file itself contains a couple of screens of the 
garbage characters noted above (I copied it and went into the copy with 
vi, LOL.), inside one particular record.

Well I don't know, but I'd guess that that particular record has become 
corrupted and is messing things up.  I'm unable to delete the record with 
ldapdelete, or modify it with ldapmodify.

Unfortunately the last good backup is two months old, so if it's at all 
possible I'd love to repair this sick id2entry.dbb.

OpenLdap 1.2 on Redhat 6.2.

Thanks for any ideas.
