Description Najmuddin Chirammal 2013-02-20 16:30:31 UTC
Description of problem: While trying to remove a tombstone entry, ns-slapd crashed with segfault. 

Version-Release number of selected component : 389-ds-base-

How reproducible: Always.

Steps to Reproduce: 
1. search for nstombstone entry
# ldapsearch -x -D cn=directory\ manager -W -b <base> objectClass=nstombstone

2. try to delete the entry.
# ldapdelete -x -D cn=directory\ manager, -W nsuniqueid=80247281-58ea11e2-8b149459-690938d9,uid=abc,cn=users,cn=accounts,dc=gsslab,dc=pnq,dc=redhat,dc=com
3. check the output (fails with ldap server un-available error)
Actual results: The delete request causes ns-slapd to segfault, the command fails with ldap server un-available.

Expected results: The entry get removed from the DS and no segfault.

Additional info: 

- I do not see the issue in older releases. (tried  389-ds-base- and 389-ds-base- ).

- ds is a part of ipa and replication is configured.

- stack trace: 

Core was generated by `/usr/sbin/ns-slapd -D /etc/dirsrv/slapd-GSSLAB-PNQ-REDHAT-COM -i /var/run/dirsr'.
