Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.
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.

Description Noriko Hosoi 2014-01-24 23:40:34 UTC 
This bug is created as a clone of upstream ticket:
https://fedorahosted.org/389/ticket/47677

1) slapi_dn_size implemented as a static function in entry.c is obsolete.
   It can be replaced with a slapi api slapi_sdn_get_size.
2) size of e_virtual_lock could be added to the size.
Comment 2 Noriko Hosoi 2014-06-26 23:50:55 UTC 
This is a part of our effort preventing the server size growth.  To verify the bug, using some long running tests (e.g., reliability), check the server size before and after.  If the delta is reasonable, we could claim this fix was verified.
Comment 3 Viktor Ashirov 2014-07-24 12:01:42 UTC 
Noriko, could you please elaborate on verification steps? 
What is meant by server size? Value of RSS of a process? 
What size of a delta is considered reasonable? Several megabytes, tens of megabytes? 
Thank you!

Viktor, unfortunately, the delta is subtle and various.  There's no clear steps to verify this particular change.

I think sanity check is good enough for this bug.

Recent reliab15 execution against build 1.2.11.15-45 running fine. No issues reported from the execution. Hence, marking the bug as Verified as Sanity only.
