Not sure how addressable this is given that it is not reproducible, but assigning to Christine to make the final call.
Remove_seen_thread has been run many many times without improperly freeing memory. I can't tell from the bug report why the memory was corrupted. We need to close this without a reproducer.
This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux release for currently deployed products. This request is not yet committed for inclusion in a release.
This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux.
Red Hat Enterprise Linux 5 shipped it's last minor release, 5.11, on September 14th, 2014. On March 31st, 2017 RHEL 5 exited Production Phase 3 and entered Extended Life Phase. For RHEL releases in the Extended Life Phase, Red Hat will provide limited ongoing technical support. No bug fixes, security fixes, hardware enablement or root-cause analysis will be available during this phase, and support will be provided on existing installations only. If the customer purchases the Extended Life-cycle Support (ELS), certain critical-impact security fixes and selected urgent priority bug fixes for the last minor release will be provided. For more details please consult the Red Hat Enterprise Linux Life Cycle Page: https://access.redhat.com/support/policy/updates/errata This BZ does not appear to meet ELS criteria so is being closed WONTFIX. If this BZ is critical for your environment and you have an Extended Life-cycle Support Add-on entitlement, please open a case in the Red Hat Customer Portal, https://access.redhat.com ,provide a thorough business justification and ask that the BZ be re-opened for consideration of an errata. Please note, only certain critical-impact security fixes and selected urgent priority bug fixes for the last minor release can be considered.
