Percona Operator for MongoDB not able to apply changes on running instance

Hi,

I have an instance of Mongodb cluster installed by Percona Operator on Openshift ( Percona Server MongoDB Operator v1.7.0).
Since a few days ago, the changes applied on the cluster instance resource definitions are not applied on the statefulsets (cfg or replicaset). The only logs I found are from the percona operator pod with this message :

Any clues on why ?

Hello @David_Da_Costa ,

that is weird. Could you please provide the exact steps to reproduce? Or at least what and how are you trying to change.

Any permission changes recently?

Hi @spronin ,

This happens when I try to change the mem and cpu limits of the replicaset.
But I don’t understand how to troubleshoot better this issue.

We didn’t change permissions or roles.
