Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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 2015-07-20 18:58:17 UTC

When trimming the retroCL, it deletes an entry. Then retrieve the entry from the cache (no creation of tombstone) to remove it from the cache.
Apparently if the entry cachen is small, it can fail to retrieve it and not testing this special condition

Fixed upstream

Comment 2 mreynolds 2015-07-21 13:48:18 UTC

Verification steps:

[1] Enable retro changelog plugin and set the retro changelog max age:

ldapmodify ....
dn: cn=retro changelog plugin,cn=plugins,cn=config
changetype: modify
replace: nsslapd-pluginEnabled
nsslapd-pluginEnabled: on
-
replace: nsslapd-changelogmaxage
nsslapd-changelogmaxage: 30

[2] Restart the server
[3] Set a very small entry cache size for the retro changelog backend

ldapmodify
dn: cn=changelog,cn=ldbm database,cn=plugins,cn=config
changetype: modify
replace: nsslapd-cachememsize
nsslapd-cachememsize: 512000

[4] Restart the server
[5] Add 2000 entries
[6] Wait 31 seconds
[7] Make sure server is still running(or did not crash during the adds)
