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 of problem:

Since upgrading from CentOS 8.3 to 8.4 and thus samba 4.12.3-12 to 4.13.3-3 we have seen the oom killer kill the epmd process on two of our IPA servers.

It looking at our 6 IPA server we see a variety of situations, from epmd not running at all, to memory usage varying quite a bit, e.g.:

VmData:   203992 kB
VmData:  1031632 kB
VmData:  2387272 kB

No idea what is expected for the epmd process.  I don't know what memory usage was like with 8.3, just that the oom kill is new.

Nothing seems to be in /var/log/samba/log.smbd.epmd

Version-Release number of selected component (if applicable):
samba-4.13.3-3.el8.x86_64
