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 02:04:46 EDT

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.
