Description of problem: when testing automation, there are about 20-25 concurrent requests sending at the same time, some operation could not be successful, eg: create app, scale up app and add cartriage to app etc, we got some error as below: 1. # rhc app create tfc1uitl python-2.7 mongodb-2.4 -s -g small --namespace gucscy --rhlogin libra-test+power7 --server stg.openshift.redhat.com Application Options ------------------- Domain: gucscy Cartridges: python-2.7, mongodb-2.4 Gear Size: small Scaling: yes Creating application 'tfc1uitl' ...

Check that you have correctly specified your OpenShift server 'https://stg.openshift.redhat.com/broker/rest/application/55dbfaeac0c5a77d8f000254/cartridges'. 4. Creating application 'zrgnzyhu' ... Unable to complete the requested operation due to: The server ex-std-node1.stg.rhcloud.com that your application is running on failed to respond in time. This may be due to a system restart. Reference ID: 0296d408de04ef1fa0e4631e9bf62227 Version-Release number of selected component (if applicable): STG(devenv_stage_1177) How reproducible: 50% Steps to Reproduce: 1. Create a bunch of apps and do some operation like scale app or add db to app Actual results: Same as description Expected results: All the operation could be successful without error. Additional info:
I believe this was an issue with the proxy configuration in STG where 503s were being returned. As of now, the number of calls resulting in 503s has been reduced greatly and these requests/tests do pass on subsequent attempts.
Test on STG(devenv-stage_1188) Issue could not be reproduced. Move bug to verified.
We apologize, however, we do not plan to address this report at this time. The majority of our active development is for the v3 version of OpenShift.
