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.

Doc Text:
description of this "Known Issue" Under specific circumstances DS can fail to close a connection that it decided to close. The consequence is new operations will not be processed and the socket will remain established creating a leak of file descriptors. In extreme scenario, leak of file descriptor can exhaust DS connection table and new incoming connection will fail. The problem can be detected with unexpected increasing number of established connections (lsof -p `pidof ns-slapd` -i TCP)

Description German Parente 2018-07-20 15:58:52 UTC 
Description of problem:

I am reporting this bugzilla because this late time we have seen ns-slapd reporting file descriptors exhaustion after RHEL-7.5 upgrade.

We cannot confirm it yet but I have seen already three customers with this issue.

We have disabled nunc-stans in one of the customers who has never come back to us again.

And we are doing this in other two cases. 

Apologies for not giving more information but we prefer to report this bug to have some investigation being done.

Version-Release number of selected component (if applicable): 389-ds-base-libs-1.3.7.5-24.el7_5.x86_64
Comment 17 mreynolds 2019-11-15 00:32:01 UTC 
nunc-stans has been abandoned, so this is issue is no linger relevant.  Closing as won't fix
