1240451 – Individual abandoned simple paged results request has no chance to be cleaned up

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.

Hi Noriko,

I Have executed the test as per mentioned steps ::
1. Acceptance test results ::
Subject: SUCCESS: Acceptance 389-ds-base-1.2.11.15-69.el6.x86_64 - 76% passed

===== [Pass/Fail] break down =====

2. I can see the pr_idx value going only up while test is running in the access logs ::

also, CPU usage is very high

3. Should I wait for the test to finish in order to get low pr_idx value ?

Thanks & Regards,

Looking at the filter test results, vfltr_97 and _99 failed although _98 passed.

I'm curious what $TET_TMP_DIR/o97, o98, o99 stored.

BTW, the test cases have a minor bug in each.  In the error case, we see the following line, but RC is not set after the $LDAPSEARCH.  You may want to add it.  Also, I'd guess this $RC should be replaced with $res???  
        message "ldapsearch either FAILED or returned entries here :$RC".

Anyway, these failures are not related to the verification of this bug...

I'd think this test gives quite a high stress to the server.

See https://fedorahosted.org/389/ticket/48375.

For this bug verification, please change the suffix "o=redhat" in paged_def.c with yours and set verified.  For the particular issue, I'm opening a bug.

Thanks.

> For the particular issue, I'm opening a bug.
Bug 1290243 - SimplePagedResults -- in the search error case, simple paged results slot was not released.

Comment 5 Amita Sharma 2015-12-10 07:52:02 UTC

Thanks Noriko,

I have verified with the updated suffix, test case working fine.

Not too much CPU usage
27578 nobody    20   0 1577m  35m  25m S 25.2  0.5   0:50.41 ns-slapd      

Also index is fine ::
  pr_idx=0

Hence marking bug as VERIFIED.

Thanks for opening separate bug
