Red Hat Satellite engineering is moving the tracking of its product development work on Satellite 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 "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. 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 "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-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 Grant Gainey 2022-08-19 19:18:31 UTC 
This bug was initially created as a copy of Bug #2062526

I am copying this bug because: 
Need to insure the fix gets backported for Sat-6.12


Description of problem:
We fixed a deadlock issue of updating timestamp in bug #2043710. Now there is another deadlock error when bulk updating artifacts. Perhaps we need to fix all places that are using the bulk_update to completely avoid the possibility of deadlock.

Comment 1 Grant Gainey 2022-09-13 13:41:05 UTC 
Closing as a dup, 2062526 is "the" BZ for fixing this in satellite-6.12
