The maximum number of microseconds the container can run at realtime priority within the Docker daemons realtime scheduler period. See Inside the container, tools like free report the hosts available swap, not whats available inside the container. The default JavaScript heap size allocated by Node.js requires additional space to smoothly run its operations; thus, creating a JavaScript issue.
