Catalog pods are failing in this cluster, as the probes using `grpc_health_probe -addr=:50051` are taking too long and reaching their timeout.

It should be noted that the probes are *successful*, but are otherwise taking too long to complete. The verbose log indicates that  

    4.12.27

    Currently ongoing with every catalog pod, but currently not seen in other clusters

    1. Marketplace operator starts catalog pods
    2. Catalog pod is scheduled and begins Running
    

    Probes fail, eventually causing pod to reach CrashLoopBackOff

    Probes succeed, pod is marked Ready

    Attempting the probe manually seems to show the probe waiting for some time before completing, reaching the timeout:
