#590 ns-slapd segfaults while trying to delete a tombstone entry
Closed: Fixed None Opened 6 years ago by nkinder.

While trying to remove a tombstone entry, ns-slapd crashed with segfault. 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=80247281-58ea11e2-8b149 459-690938d9,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) The delete request causes ns-slapd to segfault, the command fails with ldap server un-available. stack trace: Core was generated by `/usr/sbin/ns-slapd -D /etc/dirsrv/slapd-GSSLAB-PNQ-REDHAT-COM -i /var/run/dirsr'.
