OutOfMemory error in kibana-proxy container

kibana-proxy container, default value for resources.limits.memory is 96Mi, sometimes kibana pods will terminated for OutOfMemory error.
To fix this issue, you could use the following script to change resources.limits.memory from default value 96Mi to 256Mi for kibana-proxy 

for dc in $(oc get deploymentconfig --selector logging-infra=kibana -o name); do
    oc scale $dc --replicas=0
    oc patch $dc \
       -p '{"spec":{"template":{"spec":{"containers":[{"name":"kibana-proxy","resources":{"limits":{"memory": "256Mi"}}}]}}}}'
    oc rollout latest $dc
    oc scale $dc --replicas=1
done
