Sloop OOMKilled

[ravvereddy]

We are evaluating sloop by deploying it to one of our heavily used K8S Cluster where I played with multiple config options to reduce the memory consumption as per the issues and sloop config memory tweaking guid but none of them worked as expected the pod after 3 to 6 days goes into restart loop causing CrashLoopBackOff.

Here is the sts with configMap that is deployed to cluster I set the memory Limits 1.5 and requests 1.3 GB
