Add troubleshooting information to the EAP on OpenShift docs that includes advice on how to identify and troubleshoot OOM problems. This is mainly an issue for OpenShift Online, but I think it would also be useful for OCP.

From email thread with kwills@redhat.com and bilge:

I believe you should look in the event log for the pod. For logs, you
can use 'oc logs --previous <pod>' to get the application logs for the
previous pod (i.e. the one that was killed) to see what happened
within the application.

Pod restarts should be configured via the strategy in the deployment
configuration. This field specifies what will be done if a pod dies.
I believe most of the templates use Recreate or Rolling.
