Problem Note 64209: Elasticsearch clustering in SAS® Visual Investigator fails when the master node fails, and you see the message "fatal error on the network layer"
 |  |  |  |  |
When you use Elasticsearch clustering in SAS Visual Investigator, you might encounter a failure of the Elasticsearch master node with the following error messages: "fatal error on the network layer" and "java.lang.OutOfMemoryError: Direct buffer memory."
The out-of-memory error occurs due to the use of the -XX:+DisableExplicitGC Java Virtual Machine (JVM) option. This option was a default JVM option in Elasticsearch, but it was removed in Elasticsearch versions 5.5.1 and 5.6.0 onward.
The workaround is to manually remove the setting by modifying the jvm.options file within /opt/sas/viya/config/etc/elasticsearch/default/. You will need to restart the service after this change.
