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.

Comment 2 Vansen Ng 2017-12-13 06:33:39 UTC

Since Customer have a batch of server which would be online(production) soon, their monitoring system are sensitive to such "daemon.err" messages. 

So, I will put this BZ severity as high, please kindly let me know, if you have any concerns. 

Thank you

Vansen Ng

Comment 4 Ben Marzinski 2017-12-13 18:16:09 UTC

There is no good reason for them to have that severity. I'm fine with moving them down to a Notice. I'm not sure that there is time for this to make RHEL-7.5, not that I have any objection to it going in.  If the bug gets all its ACKs, I'd have no worries about making this change.

Comment 5 Vansen Ng 2017-12-14 06:09:14 UTC

Thanks for the clarification.  Please kindly check if we have any plan to fix it in coming version or we have any other reason to keep the current severity of such messages.  

Thank you
Customer Experience and Engagement, Red Hat

Comment 9 Ben Marzinski 2018-01-31 19:49:12 UTC
