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-1.3.3.1-19.el7_1
Doc Type: Bug Fix
Doc Text:
Issue 1. Cause: Asynchronous simple paged results search request code was not thread safe. Consequence: There was a small window that the simple paged result slot was conflicted and it could crash the server. Fix: The code is now thread safe. Result: No more crash is observed. Issue 2. Cause: Abandoning simple paged results request was not handled correctly if an abandon is issued too quickly. Consequence: An internal search result object had a chance not to be released. Fix: At any timing an abandon request is issued, the search result request is safely released. Result: No more memory leak is observed.

Comment 6 Sankar Ramalingam 2015-06-29 12:35:02 UTC 
1. No regression in simplepaged and filter acceptance tests
SIMPLEPAGED startup 	100% (1/1) 	  	 
SIMPLEPAGED run 	100% (17/17) 	  	 
SIMPLEPAGED cleanup 	100% (1/1)

filter startup 	100% (1/1) 	  	 
filter run 	100% (273/273) 	  	 
filter cleanup 	100% (2/2)

2. Proceeding with asynchronous simplepaged results.

Thank you so much for the valgrind output, Sankar.  It was very helpful.

Could you please try this scratch build with valgrind and see it changes the behaviour or not?

Thanks!

I copied builds from the above brew link and updated them in the same machine. Then, I created a new instance and ran the same tests with valgrind. I will update the bug after few hours.
Instance port: 19589
Inst name - testinst3

Stressed the server with the simplepaged search and I observed No crash. hence, marking the bug as Verified.
