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.

SUMMARY: AddressSanitizer: 11264 byte(s) leaked in 128 allocation(s).

Moving to ASSIGNED.
Comment 7 mreynolds 2020-01-23 14:54:50 UTC 
The patches are definitely applied, so maybe there is another leak?  Reassigning to Thierry who worked on the fix.  Viktor, what test did you run to reproduce the leak?
Comment 8 Viktor Ashirov 2020-01-23 15:33:04 UTC 
I was running dirsrvtests/tests/suites/acl/keywords_test.py (with SELinux turned off, otherwise LeakSanitizer doesn't produce any output).
Comment 9 thierry bordaz 2020-01-23 15:58:48 UTC 
yes this is a different leak,  but starting looking at it with this BZ. We may open a new one if necessary.
Comment 10 thierry bordaz 2020-01-24 10:36:27 UTC 
Backport in 1.3.10 (https://bugzilla.redhat.com/show_bug.cgi?id=1790975#c2) is failing (hang), working on a fix.
Comment 11 thierry bordaz 2020-01-28 10:15:50 UTC 
Status:
 - regression 1.3.10 fixed (use of Monitor rather than pthread_mutex)
 - failure detected https://bugzilla.redhat.com/show_bug.cgi?id=1790975#c5 is a different leak tracked with https://pagure.io/389-ds-base/issue/50857
 - Fix for this BZ is pushed upstream (be careful two commits 50709) => POST
