Description Florian Weimer 2016-07-14 14:55:26 UTC 
+++ This bug was initially created as a clone of Bug #1356645 +++

It turns out there is still a small race which can make the arena free list cyclic.
Comment 7 Joseph Kachuck 2017-03-24 18:14:45 UTC 
Hello,
RHEL 6 has entered Phase 3. In phase 3 only Critical impact Security Advisories and selected Urgent Priority Bug Fix Advisories will be accepted.
https://access.redhat.com/support/policy/updates/errata

At current this BZ does not meet these requirements. I am closing this BZ as WONTFIX.

Please reopen if this fix is required for RHEL 6. If so please also provide a justification for this fix.

Thank You
Joe Kachuck
