I have observed this as well.  I believe the problem is that for each release, Helm creates a configMap to keep data that Helm needs to manage the release.  For some of the component releases, the data exceeds the size allowed in a configMap.  (If you look at the logs for the Tiller pod in your k8s cluster, you'll see error messages about this.)

There is a Jira issue for this: OOM-2534.

Hi OOM Team,

When deploying master branch, I am seeing odd behaviour from helm.

The "deploy" cmd shows the relevant components get deplopyed:
helm deploy onap local/onap --namespace onap -f ~/onap-overrides.yaml --timeout 900
fetching local/onap
release "onap" deployed
release "onap-a1policymanagement" deployed
release "onap-aaf" deployed
release "onap-aai" deployed
release "onap-cassandra" deployed
release "onap-cds" deployed
release "onap-clamp" deployed
release "onap-consul" deployed
release "onap-dcaegen2" deployed
release "onap-dcaemod" deployed
release "onap-dmaap" deployed
release "onap-esr" deployed
release "onap-mariadb-galera" deployed
release "onap-msb" deployed
release "onap-policy" deployed
release "onap-portal" deployed
release "onap-robot" deployed
release "onap-sdc" deployed
release "onap-sdnc" deployed
release "onap-so" deployed
release "onap-vid" deployed

But when I do a "helm ls" it doesn't give me the full list of deployments:
helm ls -a

This means I cannot update or delete through helm, those components that are missing.
Has this been observed by you guys? Is it a helm plugin issue?

Any ideas?
