Review memory allocation of pods:

[psaiz]

Comments from our OpenShift colleagues:

$ oc adm top pod
NAME CPU(cores) MEMORY(bytes)
cache-2-wxtn8 1m 3Mi
logstash-deployment-6b5cdbd68f-rl7w9 20m 1569Mi
mq-1-txdvz 1m 113Mi
proxy-24-cj76v 0m 69Mi
proxy-24-ht7xc 0m 65Mi
web-16-krrxw 3m 309Mi
web-16-zxbmx 3m 215Mi
web-files-60-n2tdx 0m 155Mi
web-files-60-v7kt9 0m 116Mi

The "cache" is requesting 256Mi (seems a bit high), "logstash" is requesting 200Mi (definitely too low).
The "mq" is requesting 256Mi (seems appropriate).
"proxy" and "web-files" are requesting 2Gi each (seems much too high).
