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:
Doc Type: Bug Fix
Doc Text:
Cause: Under a very high load (hundreds of simultaneous connections and operations) the directory server could encounter a race condition in the connection handling code. Consequence: The directory server would crash. Fix: Move the code that updates the connection objects inside the connection mutex. Result: Directory server does not crash under high loads.

Description Rich Megginson 2013-04-27 01:57:35 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47349

Under heavy connection load, crashes are being randomly encountered.  This happens because we allocate and set c_private in the connection object after we put the connection on the active list.  Another thread can try to dereference c_private before it is allocated.
Comment 6 Sankar Ramalingam 2013-09-18 11:31:47 UTC 
Marking the bugzilla as Verified since no regression found with the latest build - 389-ds-base-1.2.11.15.23.
