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.

Fixed In Version: httpd-2.2.15-40.el6
Doc Type: Bug Fix
Doc Text:
The order of mod_proxy workers was not checked when httpd configuration was reloaded. Consequently, when mod_proxy workers had been removed, added, or their order changed, their parameters and scores could become mixed. The order of mod_proxy workers has been made internally consistent during configuration reload.

Hello,

It seems a patch is being proposed in the upstream bug.  I just created a support ticket here: https://access.redhat.com/support/cases/01243147/

If you get test RPMS I'm willing to test them in production.

Thanks a lot for your help.

William - thanks for filing a ticket.

Yes, we'd appreciate some testing on this patch, we'll get some test packages prepared next week.
Comment 7 Jan Kaluža 2014-10-13 06:04:46 UTC 
William, against which RHEL6 version do they need the test RPM? Can you clarify it's RHEL-6.4?

Yeah, right now I'm on RHEL 6.4 but I can upgrade my system to RHEL 6.5 if needed.

Hello Jan,

Just to be a little bit clearer, the base system is RHEL 6.4 but trying to solve this problem I decided to upgrade httpd and mod_ssl to the latest update available in RHN which was post RHEL 6.5 at the time.  This didn't solve the problem.

In a little bit of despair I tried upgrading httpd and mod_ssl to the latest 2.2.27 from a Centos repo but again this didn't solve the problem.

Obviously, for me would be a lot better to "downgrade" apache to the oficial RHEL package and as I said I'm willing to do so testing the RPMs with the patches you are working on.

Also I'm willing to upgrade the whole system to RHEL 6.5 if you want.
