steps:

1. ASSERT: make sure that you have an application with a service and replication controller running in OpenShift (ex. create an app with the nodejs-mongo-persistent template)
2. ASSERT: make sure that your memory request limit is in bytes:
3. EXEC: in OpenShift explorer, select your project
4. EXEC: in "Properties" view, select "Deployments" tab and select the last entry
5. EXEC: pick "Edit" in the context menu to it
6. ASSERT: replication controller is opened in the editor
7. EXEC: search (Ctrl+F) "limits" and make sure it has an entry for memory limits that has no unit

                       "resources" : {
                           "limits" : {"memory" : "512"},
                       },
     

8. EXEC: in OpenShift Explorer: select the service for your application and pick "Edit Resource Limits..." in the context menu
9. ASSERT: Edit resource limits wizard shows up

Result:
Memory > Limits show MiB as unit
