Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.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

Fixed In Version:	systemd-219-19.el7.1	Doc Type:	Bug Fix
Doc Text:	Under certain circumstances, by the time PID 1 adds a process to the scope unit, the process can already be ended if the process is short-running, for example an invocation to /bin/true. As a consequence, when the systemd service picked a recycled name for a scope, the following error could occur: 'Failed to start transient scope unit: Unit run-XXXXX.scope already exists.' To fix this bug, systemd-run synchronously waits until the scope unit that is being created is started.	Story Points:	---

Description Jan Kurik 2015-11-18 12:33:04 UTC

to be backported to 7.2 z-stream (EUS).

Comment 4 Branislav Blaškovič 2015-12-01 15:21:42 UTC

This bug should no longer occour in systemd-219-19.el7_2.2. Stress test added as /CoreOS/systemd/Regression/scope-unit-stress-test

But I hit another bug: BZ#1287135. It does not have any fatal consequences, so switching to VERIFIED.
