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 Orion Poplawski 2020-10-29 18:43:38 UTC 
Description of problem:

We're running Lansweeper's LSAgent on our machines.  It runs a series of commands with sudo.  This is triggering the following errors:

Oct 28 09:27:00 localhost systemd[1]: Started Session c8 of user root.
Oct 28 09:27:00 localhost systemd[1]: user-runtime-dir: Start request repeated too quickly.

Comment 1 Orion Poplawski 2020-10-30 18:01:39 UTC 
So I tried disabling the start limit, but still end up with lots of errors:

This feels pretty heavy-weight for just running some sudo commands, especially by a daemon.
Comment 2 Orion Poplawski 2020-11-20 14:36:15 UTC 
This may be fixed in 8.3, at least I'm not seeing it on my one RHEL 8.3 VM.  I'll know more once CentOS 8.3 is out and my other machines update.

Comment 5 Orion Poplawski 2020-12-16 17:01:56 UTC 
Hmm, looks like we can still run into the original errors as well:

Comment 8 David Tardon 2021-03-22 08:45:34 UTC 
Can you try with testing rpms from http://people.redhat.com/dtardon/systemd/bz1642460-backport-UserStopDelaySec=/ ?
Comment 9 Tommy Doucet 2021-10-21 15:43:53 UTC 
Customer seems to be hitting this issue in OpenStack in case 03051999. does this have any impact or can these be safely ignored? Thanks!

This has been in this state for a while now. Any update on this? Can this issue be safely ignored?

Thank you!
Comment 11 Orion Poplawski 2022-01-31 18:47:57 UTC 
I don't think I'm seeing any more errors with systemd-239-51.el8_5.3.x86_64
Comment 12 Lukáš Nykrýn 2022-05-31 13:53:14 UTC 
This bug seems to be fixed in 8.5 and above, so let's close this. If you encounter this issue on newer version feel free to reopen the bug.
