Failed to install ror_kbn 1.16.33_es_6.5.1

Hi Simone, I’ve tried to install the kbn plugin but it fails. I saw a forum and I set
an env.variable $NODE_OPTIONS --max-old-space-size=4096 , but the installations was unsuccessful too.

What should I do?

Try to stop all the service daemons in that server, free up some memory, and try again.
