RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Nathan Kinder 2013-11-05 17:46:32 UTC
+++ This bug was initially created as a clone of Bug #1026931 +++

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47577

Steps:
1) setup up 2 way MMR
2) make sure the entry cache is full, so that search requests must evict old entries from the cache to make room for new entries
3) generate an ADD load against one of the masters
4) repeatedly search for (objectclass=nsTombstone) from the base suffix

--- Additional comment from Rich Megginson on 2013-11-05 12:44:26 EST ---

Steps to reproduce:

1) setup one instance of directory server with suffix dc=example,dc=com
2) Use ldclt like this to add a lot of entries:
    ldclt -h $HOST -p $PORT -D "$LDCLTDN" -w "$LDCLTPW" \
        -e add,person,incr,commoncounter,noloop \
        -r1 -R1000000 \
        -n8 \
        -f CN=XXXXXXX -b DC=EXAMPLE,DC=com \
        -q &
3) sleep 120 to allow some entries to search/mod/del
4) Use ldclt like this to do a lot of modifies:
    ldclt -h $HOST -p $PORT -D "$LDCLTDN" -w "$LDCLTPW" \
        -e incr,commoncounter,attreplace=sn:valueXXXXXXXXXX \
        -r1 -R1000000 \
        -n8 \
        -f CN=XXXXXXX -b DC=EXAMPLE,DC=com \
        -q &
5) sleep 30 to allow mods to progress
6) Use ldclt like this to do a lot of deletes:
    ldclt -h $HOST -p $PORT -D "$LDCLTDN" -w "$LDCLTPW" \
        -e delete,incr,commoncounter,noloop \
        -r1 -R1000000 \
        -n8 \
        -f CN=XXXXXXX -b DC=EXAMPLE,DC=com \
        -q &
7) use ldclt like this to do a lot of searches:
    ldclt -h $HOST -p $PORT -D "$LDCLTDN" -w "$LDCLTPW" \
        -e esearch,incr,commoncounter \
        -r1 -R1000000 \
        -n8 \
        -f CN=XXXXXXX -b DC=EXAMPLE,DC=com \
        -q &

You should see a crash within 10 minutes or so
