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.

Fixed In Version: 389-ds-base-
Doc Type: Bug Fix
Doc Text:
.Directory Server now also applies limits for maximum concurrent `cleanAllRUV` tasks received from extended operations Directory Server supports up to 64 concurrent `cleanAllRUV` tasks. Previously, Directory Server applied this limit only to manually created tasks and not to tasks the server received from extended operations. As a consequence, more than 64 concurrent `cleanAllRUV` tasks could run at the same time and slow down the server. This update adds a counter to track the number of clean tasks and abort threads. As a result, only up to 64 concurrent `cleanAllRUV` tasks can run at the same time.

Description mreynolds 2019-08-08 17:16:13 UTC
Description of problem:

There is a limit on the number of cleanAllRUV tasks that can be running at once.  But this limit is not checked for incoming replicated tasks.  It is only checked when the original task is created.  This can allow for thousands of clean tasks/threads to be created.

The limit needs to be checked when cleanallruv extended operations are received.

This bug is created as a clone of upstream ticket:
