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.

Comment 4 Pavel Moravec 2016-09-04 08:18:54 UTC

The backtrace suggests https://bugs.ruby-lang.org/issues/9859 is hit. That BZ is fixed in upstream but not in ruby-2.2.2.

Comment 6 Ivan Necas 2016-12-14 14:05:31 UTC

I have not seen any occurrence of this issue in pretty large sample, which makes me think it's not reproducible anymore. Ruby scl had updates in the meantime so there is a chance it has already been fixed. Closing now. If this issue appears again with later releases. Please re-open the issue.
