I think this should make it in 6.1 z-stream. Upstream merged. Low effort.
Comment 4 Bryan Kearney 2015-11-02 11:02:57 UTC 
Upstream bug assigned to ddolguik
Comment 5 Bryan Kearney 2015-11-02 11:03:00 UTC 
Moving to POST since upstream bug http://projects.theforeman.org/issues/12319 has been closed

I was trying to verify this bz with given script and steps in comment 7 and 8. However, looks like port 8000 is not valid. 

hwoever, with port 8443, I'm getting following output.  

[root@cloud-qe-6 ~]# ./racetest.sh http://localhost:8443 b9d50b5c-23a3-4a66-b4d2-9f18cafc7db9 5
[root@cloud-qe-6 ~]# 





Is this expected result, please confirm ? thanks

Please take a look at attachment.
Comment 14 Lukas Zapletal 2016-01-18 08:56:38 UTC 
Oh port is the smart proxy port, which is usually 9090, 8448 or 8443 according to your configuration. You must see request logs in proxy.log.
Comment 15 Sachin Ghai 2016-01-18 10:07:32 UTC 
Thank you Lukas.

Verified with in 6.1.6 compose #5

On concurrent requests, I don't see error reported in original bug request. I tried with 1500 requests concurrently.
