Whenever we start the operator, memory consumption goes upto 20GB and our api server becomes unresponsive. API server starts consuming more than 15GB and then it gets killed and the master becomes unhealthy.

we have to scale down the namespace-config operator for making api server responsive again. what could be the reason that it consumes too much memory once it starts? could there be some memory leak? Is it possible that it reconciles resources in chunks rather than reconciling all together? how can we find the root cause?
