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 German Parente 2017-11-22 12:49:28 UTC 
Description of problem:

this is a copy of 

https://pagure.io/389-ds-base/issue/49463

When cleanAllRuv is launched, it spawn cleanAllRuv on all replicas.
Each replica will clean its changelog and database RUV but in addition will DEL the keep alive entry of the target ReplicaID.
So for the same entry (keep alive) there will be as many DEL as there are replicas

Those DEL are replicated. The DEL will attempt to DEL an entry that is already a tombstone.
Locally this update is considered as a NOOP.

The problem is that the NOOP does not update the RUV. So the supplier will loop sending the DEL.
Package Version and Platform

This problem is a side effect of https://fedorahosted.org/389/ticket/48278
It exists since 1.3.6
Steps to reproduce

Run the attached test case
Actual results

DEL of the cleaned RID can be replicated several times
Expected results

Either the DEL should not be replicated, or it should update the RUV
