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 Rob Crittenden 2023-07-31 13:02:57 UTC 
+++ This bug was initially created as a clone of Bug #2209636 +++

Description of problem:
Freshly installed replica is leaking memory. From the valgrind output it seems it's actually libipa_otp_lasttoken plugin library:

The leak summary gives this ( 2,5 MB definitely lost overall + 350K indirectly lost ) :

==23733== LEAK SUMMARY:
==23733==    definitely lost: 2,493,525 bytes in 66,549 blocks
==23733==    indirectly lost: 347,788 bytes in 34,963 blocks
==23733==      possibly lost: 3,818 bytes in 9 blocks
==23733==    still reachable: 3,897,465 bytes in 40,026 blocks
==23733==                       of which reachable via heuristic:
==23733==                         stdstring          : 30 bytes in 1 blocks
==23733==         suppressed: 0 bytes in 0 blocks
==23733==

==> libipa_otp_lasttoken plugin seems to be involved here ...
