DN index delete failed



I am running Buchan Milne's build of openldap-2.3.43-1.rhel5.x86_64 on a
RedHat 5.2 system running kernel 2.6.18-92.1.6.el5. in a VMware instance.

This system runs as a master to 3 other syncrepl slaves. Very few
queries are made against this system, it is simply a central place to
direct updates to. Writes are infrequent, averaging 4-5 and hour.
Databases are hdb.

This system was running openldap-servers-2.3.39-3.rhel5.x86_64 for
several months until a few days ago when I did a update via yum pointing
to http://staff.telkomsa.net/packages/rhel5/openldap/x86_64/

This system has been running without issues until last night. Then this
appeared in the logs during deletion of a user account:

Jul 25 02:41:51 janus slapd[31075]: conn=7142 op=1 DEL dn="uid=pcass,ou=People,dc=une,dc=edu,dc=au" 
Jul 25 02:41:51 janus slapd[31075]: conn=7142 op=1 RESULT tag=107 err=80 text=DN index delete failed 

Other accounts have been deleted before and after this event. Further
attempts to delete this particular entry always fail with the same
error.

In an attempt to fix this, I shutdown slapd, ran /usr/bin/slapd_db_recover
in the /var/lib/ldap directory and restarted slapd.

Attempting to delete the entry after this produced:

Jul 25 14:20:14 janus slapd[15043]: conn=3 op=1 DEL dn="uid=pcass,ou=People,dc=une,dc=edu,dc=au" 
Jul 25 14:20:14 janus slapd[15043]: conn=3 op=1 RESULT tag=107 err=32 text= 

Further attempts return us to:

Jul 25 14:24:54 janus slapd[15043]: conn=19 op=1 DEL dn="uid=pcass,ou=People,dc=une,dc=edu,dc=au" 
Jul 25 14:24:54 janus slapd[15043]: conn=19 op=1 RESULT tag=107 err=80 text=DN index delete failed 

Searching the list, I see similar problems mentioned in these threads:

There did not seem to be any resolution to these however.
