@JohnStarich, have deleted the cluster in the meantime. I tested it today on totally fresh new cluster, but now the default resource limit is fine and enough
and yes, #199 could be the same (root) cause
regarding the PR, I have currently no clue about the topic :-D

When I've installed ibmcloud-operator I've been using a subscription that looks like this:
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
name: ibmcloud-operator
spec:
channel: stable
name: ibmcloud-operator
source: community-operators
sourceNamespace: openshift-marketplace
config:
resources:
limits:
cpu: 400m
memory: 700Mi
requests:
cpu: 400m
memory: 40Mi
This is probably oodles more than the operator itself needs 🤷 .
The increased memory consumption in OpenShift when compared against other cluster types might be related to the number of namespaces present in the cluster itself - especially if your installing the operator with cluster-wide scope.

Thanks for opening @haf-tech. I think this is likely a duplicate of #199
How many secrets are in your cluster? kubectl get secrets -A | wc -l

If either of you are interested, we’re open to PRs for fine-tuned watches. It looks like they would significantly reduce memory usage.

after applying the first Service
and Binding
, seeing OOMKilled
oc get secrets -A | wc -l
1258
the above edit (increasing resource limit) helps here
from cloud-operators.
Yeah, looks like the same issue. Let's focus our conversation in #199. @greglanthier you're welcome to take this on, if you're interested.
