Description of problem:
Got below error when I try to deploy logging-kibana with 'oc deploy logging-kibana --latest'

Error from server: 502:  (unhandled http status [Request Entity Too Large] with body []) [0]


Version-Release number of selected component (if applicable):
openshift v3.0.2.903-74-gf49cee6
kubernetes v1.2.0-alpha.1-1107-g4c8e6f4
etcd 2.1.2

How reproducible:
sometimes

Steps to Reproduce:
1.deploy EFK stack according to :
https://github.com/openshift/origin-aggregated-logging/tree/master/deployment

2.wait for the deployments complete and found both deployments are error.
(both deployment fail because pods took longer than 600 seconds to become ready)
[root@dhcp-128-16 ~]# oc get pods
NAME                           READY     STATUS        RESTARTS   AGE
logging-deployer-6hb70         0/1       Completed     0          23m
logging-es-36n5hs16-1-deploy   0/1       Error         0          19m
logging-kibana-1-deploy        0/1       Error         0          19m

3.
deploy logging-es-36n5hs16 with 'oc deploy logging-es-36n5hs16 --latest', the deploy pod starts.
then try to deploy kibana with 'oc deploy logging-kibana --latest'

Actual results:
[root@dhcp-128-16 ~]# oc deploy logging-kibana --latest
Error from server: 502:  (unhandled http status [Request Entity Too Large] with body []) [0]

Expected results:
deployment should start correctly
