1431207 – ns-slapd killed by SIGABRT

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.

Comment 4 wibrown@redhat.com 2017-03-13 00:58:06 UTC

I think I need a test to help with this. It looks like something is putting a stack value into the vattr map, which triggers the abort on free. (can't free off the stack).

If we have a test to reproduce this, that would make this a lot easier to track down and resolve, but I can see how the memory leak fixes would resolve this.

The issue is we shouldn't just roll back this fix because we have a lot of leaks, and we need these fixes. It's just a pain that we found it so late :(

Comment 5 mreynolds 2017-03-27 18:37:45 UTC

Is this fixed? I don't see an upstream ticket?

Comment 6 Viktor Ashirov 2017-03-28 14:05:23 UTC

I can't reproduce it with the new build. Looks like coverity fixes helped.

Comment 8 Viktor Ashirov 2017-04-06 11:20:32 UTC

Build tested:
389-ds-base-1.3.6.1-6.el7.x86_64

No crashes were observed with this build, marking as VERIFIED.
