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 Corey Marthaler 2014-09-12 19:26:42 UTC 
Description of problem:
I've been seeing these failure messages while running cmirror configuration tests. They don't appear to cause any problems however, just worrisome to see in the logs.

Comment 2 Peter Rajnoha 2014-09-15 10:30:32 UTC 
This seems to be corosync internal error - there's also https://access.redhat.com/solutions/45952 for this issue - so this must have happened at least once before... As such, I'd probably reassign this to corosync component to debug this more.

Patch to fix

This is the old 'finalise being called in the dispatch' routine race. The solution I chose is to return CS_OK from coroipcc_dispatch_put() if the ipc_channel has been closed. It's been tested and works for me.

I'll post it to the mailing list for review.

    ipcc: Fix ERR_LIBRARY error if finalise called inside dispatch
Comment 7 Christine Caulfield 2015-02-27 16:30:12 UTC 
We're fixing a benign message in an obscure part of the code. I don't see the need to document this BZ
Comment 10 Corey Marthaler 2015-04-22 23:12:27 UTC 
Fixed verified in the latest rpm (corosync-1.4.7-2.el6.x86_64).

I was unable to reproduce these errors after hours of running the test listed in comment #0.
